The RaTio DRillRange Setting the standard in tool life,accuracy and speed:- RT 100 - RT 150 new: RT 100 R
with radius point geometry
RT 100 T up to 30 x D
Perfect combination:Ratio drill and hydraulic chuck for optimal machining results
The name says it all: Ratio drills considerably reduce
machining costs, especially in expensive machining
centers, flexible machining systems and transfer
lines. Ratio drills offer a new dimension, particularly
with regard to quality and quantity. Ratio drills are
high performance tools; our answer to the latest
developments in machining technology:
• highspeedmachining(HSC)
• drymachining
• quasidrymachining
(minimallubricationtechnique,dryHSC)
• machiningofnewmaterialssuchasADIandGGV
• high performace machining of deep holes up to
30xDinsteelsandcastalloys
To take full advantage of the cutting capacity availa-
ble from the latest machining systems, Guhring
Ratio drills, depending on design, offer the follow-
ing special advantages:
• Extremelyhighspeedandfeedrates(seeGurogui-
de).Atspeedsaboven=6,000rev./min(seeHSC!)
thesafety regulationsof theVDIguidelinesmust
be observed.
• Exceptionaltoollifeastoolsaremadefromcarbi-
de (ultra finegrainquality) carefullyproduced in
our own carbide plants, the majority of which are
coated.
• Innovative point geometries such as the radius
pointgrind(patentpending)oftheRT100Rcreate
new possibilities for the machining of difficult-to-
machine materials.
• Improved positional and dimensional accuracy
of hole are further advantages of our latest point
geometries.

Manufacturing specificationsPoint grinding: relieved cone with honed cornerPointangle: 140°Web thinned: Ratio web thinningTolerance on Ø: m7
Range of applicationFor the drilling of short-chipping materials such as cast iron, grey cast iron, spheroidal and malleable cast iron, aluminium alloys with high silicon content. Ultra fine car-bide grade makes this tool ideally suited for the drilling of abrasive materials.
Type RT 100 F
Manufacturing specificationsPoint grinding: relieved conePointangle: 140°Web thinned: Ratio web thinningTolerance on Ø: m7
Range of applicationIdeallysuitedfor thedrillingofhigh-alloyedsteels,stain-less, acid and heat resistant steels, Inconel, Hastelloy,Monel, including brass, bronze, aluminium and magnesi-um, aluminium and magnesium alloys as well as titanium and titanium alloys, sintered metal.
Type RT 100 U
Manufacturing specificationsPoint grinding: relieved cone with honed cornerPointangle: 140°Web thinned: Ratio web thinningTolerance on Ø: m7
Range of applicationFor the drilling of long- and short-chipping materials such as structural and case hardened steels, cast steels, heat-treatable steels and alloyed steels with a tensile strength of up to approx. 1200 N/mm2, including carbon steels, bronze,castironandhigh-alloyedAlSi-alloys.

Intermediate dimensions for conventional coolingInadditiontotheex-stockrangeGuhringstilloffersRT100T drills as special tools to specific customer requirements. For conventional cooling we realise intermediate diameters withmaximumdrillingdepthsupto30xDoratotallengthup to max 400 mm.
Special design: RT 100 T drills for minimum quantity lubri-cation (MQL)Forminimumquantity lubricationRT100Tdrillsareonlyavailable as special tools. The MQL tools are produced with a special shank end optimised for MQL machining. Coolant ducts and flutes are also designed especially toMQL requirements. The MQL special tools are available withdiametersfrom3.0upto16.0mmandmax.drillingdepthsupto30xDoratotallengthuptomax.400mm.Asonlyanextremelysmallamountofcoolantisappliedforminimal lubrication, the delivery of the coolant to the most effective location is of extreme importance. The tapered shank end, developed by Guhring, optimally satisfies theconditions relevant for minimal lubrication applications: It prevents neat oil from consolidating and offers simplehandling characteristics and cost-effective production.IncombinationwithGuringhydraulicexpansionchucksandGuhring‘sMQLcoolantdeliveryset,itoffersanoptimalandcost-effective solution for MQL machining with highest bore hole quality and outstanding lifetime.

Ratio drills
Typical hole quality characteristics, produced in 42CrMo4V with TiN-coated HSS drills and Ratio drills.
The overall total of the maximum positive and negative deviations is the sum of the total run-out in relation to the blackcircleasmeasuredonstandardinstruments(dRmax).The red lines at the hole centres indicate the direction and amplitudeof thedisplacementsAS (AxisShifting)of theproduced hole from the true center point.The parameter showingthelargestdeviationisdecisivefortheITqualityclass of the hole in relation to the tool diameter.
The black circle in the diagram represents the nominal hole diameter which the tool should ideally produce. The red circle indicates the form actually produced. The mean value of the radius of the red circle, i.e. the average diame-ter, isshownbythebluecircle (withRatiodrills theave-rage diameter is practically identical to the actual diameter produced).

For safety reasons it is very important, that a drill doesnot exceed a speed of n = 6 000 rev./min when not supported.The centrifugal forces could break these long tools beforereaching the workpiece surface!

External cooling recommendations RT 100 R:We recommend using soluble oil or neat oil. WithRT100R, cooling with air is also possible under certain conditions. However,theapplicationunderMQLconditions,forwhichthetools are extremely well suited, is always preferable. For MQL applications we recommend the tapered MQL shank endaswellastheMQLcomponentsfromGuhring.Further information is available on request.

gM 300 The MoDulaR Tooling SySTeM
• to ISO 12 164, DIN 69 893 and DIN 69 871• for transfer lines, machining centers and lathes
The Guhring Ratio drill with plain shank and the GM 300 system are the ideal partners for a cost-efficient and highly accurate production:
• the Ratio drill as well as the GM 300 system are specifically adapted to the current trends in production technology and are ideally suited for high speed machining (HSC), dry machining as well as minimal quantity lubrication MQL.
• the two programs perfectly satis-fy the requirements for machining centres, flexible production sys-tems as well as transfer lines and combined with each other achieve optimal results.
• the high precision provided by the GM 300 tool holder is of additional benefit to the above average posi-tional and dimensional accuracy of the Ratio drills.
HT 800 WP - RT 800 WP - LT 800 WP
The interchangeable insert drilling system T 800 is the intelligent so-lution for efficiently and economically machining large and deep ho-les applying the following types:
HT 800 WP: • Tool holders for drilling depths up to 3 x D, 5 x D and 7xD• interchangeable inserts with surfaces bright, TiN or Fire • for bore holes from diameter 11.5 to 25.99 mm
RT 800 WP: • Tool holders for drilling depths up to 3 x D, 5 x D, 7 x D • interchangeable inserts with surfaces bright, TiN or Fire• for bore holes from diameter 16.0 to 40.5 mm
LT 800 WP: • Drilling system for drilling depth up to 12xD • interchangeable inserts with surfaces bright, TiN or Fire• for bore holes from diameter 40.0 to 100.0 mm
