BTM’s Tog-L-Loc and Lance-N-Loc joining systems produce clean, strong and consistent joints in most coated or uncoated metals. The joints are characterized by a “button” formed on the die side layer of metal and a re-cess formed in the punch side layer. The button is a good indicator of joint quality and therefore, simplifies quality control. Two or more layers of metal typically ranging in thickness from .008” (0.2mm) to .157” (4.0mm) per sheet can be reliably joined in most cases.
Punch Side
Tog-L-Loc® Lance-N-Loc®
Tog-L-Loc is a circular, leak-proof joint formed by drawing the metals into a circular “cup” and expanding the diameter to form a 360o lock below the bot-tom sheet.
Tog-L-Loc is generally preferred due to its omnidirectional strength characteristics, excellent fatigue properties and exceptional tool life.

Lance-N-Loc is commonly used where metals are insufficiently ductile to join with Tog-L-Loc or in certain dissimilar combinations or multiple layers.
Lance-N-Loc is a joint formed by lancing the metals on 2 sides, drawing them through the thick-ness and expanding the width to form a lock on 2 sides.

1. The Force Mechanism:A device capable of producing suffi-cient force to form the joint(s). Hydrau-lic, pneumatic or mechanical presses are generally used.
2. The Force Frame: Forces must be contained to prohibit flexing at the punch / die. Deflection will cause degraded joint strength and tool breakage.
A Tog-L-Loc / Lance-N-Loc system consists of 5 major components.
Lance-N-Loc Punches
Standard
3. The Tog-L-Loc / Lance-N-Loc Punch:Tog-L-Loc punches are available in various tip diameters (see joint size page 5), lengths and styles to suit differing application require-ments. The perimeter of the round Tog-L-Loc punch tip has a slight radius to prevent piercing. Lance-N-Loc punches are also available in various lengths and styles. The square Lance-N-Loc punch tip has cutting edges on two sides and angular ramps on the other two.

4. The Stripper:
Blade shields are supplied with several die styles. These shields protect the die blades from the force of the stripper and help to retain the blade assembly to the die. In some cases, dies are mounted in pockets within a block which functions as the shield.
Tog-L-Loc dies are available in many styles to suit differing application requirements. The dies have a fixed anvil which is recessed from movable or pivoting blades. A radius is given to the blades’ inside edge. Dies are retained by ball lock, set screws or socket head cap screws. The 940 Tog-L-Loc and Lance-N-Loc dies feature a one piece anvil and shield. A spring is used to close the 940 blades.
Lance-N-Loc dies are also available in various styles, however, all are two bladed. The blades have cutting edges to the inside, with a fixed anvil recessed from the blade surface.
5. The Tog-L-Loc / Lance-N-Loc Die:
Lance N-Loc (Special Dies)
Both Tog-L-Loc and Lance-N-Loc require use of a spring stripper / clamping mechanism which sur-rounds the punch tip. The stripper must preload the parts before punch entry, and must allow full punch travel. The spring force must be sufficient to clamp the parts together during joining and prohibit up-ward extrusion of the metal around the punch.

Punch Side Metal
Tog-L-Loc® and Lance-N-Loc® tools come in three standard joint sizes, expressed as the punch tip diameter or width. The correct joint size for a given application is determined by the following:
1. Thickness of metal being joined.
2. Available clearance or flange size.
3. Strength required of each joint.
Refer to charts on pages 9, 13, & 17.

Tooling Descriptions
The Tog-L-Loc® punch and die are ordered from BTM to join a specific combination of metals
The tooling can be optimized for maximum joint strength, or generalized to join a wider range of metals.
A spring pressure pad / stripper is required surrounding the punch for proper forming of the Tog-L-Loc® joint.
The formed button is measured for non-destructive checking. Button dimension or "BD" is specified by BTM, and tolerancegages are available for simplified check-ing.

2. Choose the correct tool numbers from the charts.Tog-L-Loc® tools are "tuned" for the metals you will be joining. The charts (pages 20-22) reference joint size, metal thickness, and tool length. Various tool lengths allow access to differing part configurations and die designs. Special tool holders may be fabricated when necessary to access difficult parts.
BTM offers consultation for tool selection, and will join sample parts and pro-vide strength test results for your evaluation. A handling charge is applied to this service, contact BTM for details.
TOOL SELECTION
1. Determine which joint size to use.Joint strength increases with joint size (see example). Force required to produce the joint also in-creases, as does the physical size of the tooling. Choosing the correct joint size for a given application involves determining the strength required of each joint, and accessibility of the joining site. The 4,6 joint is the most commonly used size in practical application.

BTM sheet metal joining tools are furnished with joint data documentation expressed in the following terms.
Joint Size: 1. Expressed as the punch tip diameter (Tog-L-Loc) or width of the die anvil (Lance-N-Loc). For example, a .18” Tog-L-Loc has a punch tip diameter of .180” (4.6mm). Common sizes are: .12” (3.0mm), .18” (4.6mm), .22” (5.5 mm) and .25” (6.4mm) with special sizes used on occasion.2. PTR: (Punch Tip Radius): Tog-L-Loc only. Expressed as a decimal figure example: .010’’ (0.25mm). This dimension is determined at BTM to suit the ap-plication. There are two available radii; 0.010” and 0.020”

4. AD (Anvil Depth): Depth from the top of the die blades to the top of the die anvil. Expressed as a decimal figure Example: .035’’ (0.9mm). This dimen-sion is determined at BTM to suit the application.
Joint quality (strength) is monitored by measurement of the button dimension (BD). Button dimension is controlled by adjusting punch penetration. Button dimensions specified by BTM are intended to give the optimum combination of joint strength and tool life. BD specification includes a tolerance to accomodate standard mill tolerances in the metals.

In order to function reliably, a Tog-L-Loc or Lance-N-Loc system must conform to the following guidelines.
The parts to be joined must allow adequate access for the tooling and mate without gaps at the joint locations.
1.
3.
4.
The metals to be joined must be sufficiently ductile, within the thickness capabilities of the system and the parts must conform to the tolerances the machine was designed around.
The machine must consistently produce sufficient force to form the joints.
The machine must contain the force without excessive flexing.
The stripper/clamp must apply sufficient force to contain the flow of metal within the die.
The tooling must be appropriate to the metals being joined, (i.e. Tog-L-Loc or Lance-N-Loc, joint size, AD and PTR.) Tools purchased for one metal type and thickness may not give the best results with a different metal.
The tooling must be adjusted & aligned to properly form the joints, and be secured to maintain these settings.
The machine and tooling must be maintained properly so that all components perform their intended function. For example, worn seals can reduce force output thereby affecting joining ability.

How to use these Die ChartsEach Die Chart contains information on what punch and die to use with different thicknesses of metal. In addition the chart gives the shear and peel strength for previously tested joints. It should be noted that each chart contains generalized data for mild steel. For optimum strength values, samples of specific alloys and coatings may be submitted to BTM for testing.
Abbreviations Used:A - Punch Length (listed first in millimeters then in inches)B - Die Length (listed first in millimeters then in inches)PTR - Punch Tip Radius (listed in inches)AD - Anvil Depth (listed in inches)BD - Average Button Dimension (listed in both millimeters and inches)
Charts are sorted by Die Side metal thickness (second column) and then by Punch Side metal thickness (first column).

Design Parameters

General Design Guidelines
The punch should be guided a minimum of 1.12″ (28.4mm) in the punch retainer.
The location tolerance to the centerline of the punch hole should be ±.0005” (.01mm)
The “940” punch mounting is preferred. While the set screw method is still acceptable.
If possible use a 5/16 - 24 set screw to retain a whistle notch punch, ¼ - 28 should be the mini-mum. The set screw should be perpendicular to the centerline of the punch.
The punch should have some means of adjustment. A backing plate or set screw behind the holder would be an example.
The hole and tolerance for a standard ⅜” diameter punch would be: Ø.3750 +.0002 / -.0000 (9.525mm +.0051 / -.0000)
The hole and tolerance for a standard ½” diameter punch would be: Ø.5000 +.0002 / -.0000 (12.7mm +.0051 / -.0000)
The surface that the punch seats on should be through hardened. Typically, this material is 6150 with a hardness of 50-54 on the “C” scale.

“940” Series Die Assembly The location tolerance to the centerline of the die hole should be ±.0005″.
940 series dies require a knock out hole from the back side.
Because the 940 die has a built in blade shield the top of the die should not be flush with the detail it’s mounted in. If anvil strength is not an issue, the typical design method would expose the ring of small holes in the guard can.
The 940 die is better suited for applications exposed to coolants and lubricants.
Compared with a set screw, the 940 retention method is less likely to come loose during normal machine cycling.
3 Bladed Elastomer The location tolerance to the centerline of the die hole should be ±.0005″.
3 bladed style “A” dies require a knock out hole from the back side.
3 bladed style “A” dies should have as much material protecting the blades as possible.
Due to incompatibility between specific components of die compounds and the standard Polyurethane (Yellow) Elastomer Rings, (2) alternative Elastomer Rings may be used.
Following is a basic guide for usage of the alternatives.

Strippers should be made of 6150 steel, with a hardness of Rc 50-54.
Contact Force is when the punch contacts the work piece.
The recommended stripper contact force for .12 TL is 200 lbs./joint. The recommended stripper contact force for .18 TL is 300 lbs./joint.
The recommended stripper contact force for .22 TL is 525 lbs./joint.
The recommended stripper contact force for .25 TL is 750 lbs./joint.
The location tolerance to the centerline of the punch clearance hole(s) should be ±.005″.
The location tolerance to the centerline of the shoulder screws should be ±.0005″.
The basic dimensions for strippers are shown below.
When using round tip strippers, tip diameter should be larger than thedie pocket diameter. Use shoulder screws from Unbrako or similar

Lance-N-Loc is a rectangular joint formed by drawing the metals into a rectangular “cup” and then expanding the sides to form a lock below the bottom sheet.
A stripper clamps the metals between the punch and the die guard
The lateral flow of metal is accommodated bt the patented moving (self-cleaning) die blades, forming a lock of greater width than the drawn section which accounts for high strength of Lance-N-Loc. This entire sequence taked place in a single motion or press stroke.
The punch shears two edged & draws the metals into the die.
The punch continues to travel, squeezing the metals.
As the punch retracts, the stripper al-lows the punch to be removed.

Page Title
General Design GuidelinesThe punch should be guided a minimum of 1.12″ in the punch retainer.
The location tolerance to the centerline of the punch hole should be ±.0005”
The Ball Lock punch mounting is preferred.
The punch should have some means of adjustment. A backing plate or set screwbehind the holder would be an example.
The hole and tolerance for a standard ⅜ diameter punch would be: Ø.3750 +.0002 /-.0000
The hole and tolerance for a standard ½ diameter punch would be: Ø.5000 +.0002 /-.0000
The surface that the punch seats on should be through hardened. Typically, thismaterial is 6150 with a hardness of 50-54 on the “C” scale.
