The inner cutting edge of a competitors drill fractured.

Please ensure the highest rigidity possible exists in both machine set up and workholding.

Refer to the following graph for coolant pressure and volume. Coolant is an important factor in the efficient use of these drills.

Use on a lathe(1) The inner cutting edge must

be positioned between 0-0.2mm over center.

Cannot be used for stack drilling.In common with many indexable insert drills, these drills produce a round disc on exit which unless evacuated may cause the drill to fracture.

(2) To adjust the hole diameter by off-setting the drill, the outer cutt ing edge and machine axis must be set parallel.

(3) When producing an oversize hole. The drill offset should be no more than 2% of the diameter. It is not possible to produce an undersized hole.

(4) When through hole drilling on a lathe the disc produced by the drill exiting the workpiece may be expelled at high velocity. To reduce the danger of injury or damage a cover guard is highly recommended.

*Increase Suitable TAF Drill

Guideline for selecting adjust fit sleeve

Application of the JUST FIT SLEEVE

<Tool Selected>Drill :JUST FIT SLEEVE :

(Eg.) Desired diameter is 20.3mm (oversize is taken as 0.1mm)Desiredø = (Drillø + Increase of JFS) + 0.1mm

20mm drill Using JFS an increase of 0.2mm

Oversize

Note : Oversize can vary due to the cutting conditions used, please use the above as a guideline.

1 When inserting the drill into the side lock holder, align the V groove on the outer peripheral edge of the drill flange, the round holes of the outer peripheral edge of the sleeve flange and the screws of the side lock holder for fixing the drill.(If the drill does not have a V groove, align the notch of the drill shank with the round holes of the sleeve.)

2 Insert screw A of the side lock holder directly through the open window of the sleeve to clamp the drill. Tighten screw B to a degree so not to damage the sleeve.

Note:Fine adjustments cannot be made for the diameter of the sleeve.Cannot be used with collet chuck type holders.

Ordering the JUST FIT SLEEVEPurchasing Method 1Oversize can vary due to the cutting conditions used. Therefor it is recommended to purchase as a set. When placing an order, please the Set order number.(5 sleeves/set)

Purchasing Method 2It is possible to order individually. When placing an order use the individual order number.

For Your SafetyDon't touch inserts and chips without gloves. Please machine within the recommended application range, and exchange expired tools with new ones in advance of breakage. Please use safety

cover and wear safety glasses. When using compounded cutting oils, please take fire preventions. When attaching inserts or spare parts, please use the attached wrench or spanner. When using rotating tools, please make a trial run to check run-out, vibration and abnormal sounds etc.
