Guhring GT100 Jobber Drills HSS

HSS GT100 jobber drills. For drilling in difficult conditions when swarf congestion prevents an adequate flow of coolant. For use in steel and cast iron having a hardness of up to 1000N/mm2. Not recommended for nickel-chrome steels or similar material. Manufactured to BS 328/DIN 338.

Series 549 - Metric

Guhring Centre Drills HSS

Designed with spiral flutes and various lengths and forms to give high quality centre holes that suit most applications. 60 inclusive angle. Manufactured to BS328:Part 2:1986, DIN333A, ISO866, ISO2540, ISO2541.

For all dimensional specifications please refer to our catalogue.

Series 292 - Inch

Guhring Production Jobber Drills HSS-Co 5%

Rigid, high-heat resistant drill with large helix angle of 35. Suited for titanium and titanium alloys, stainless steels and heat resisting austenitic steels. Limited suitability for special alloys such as hastaloy, inconel, nimonic etc. Manufactured to DIN338.

Series 605 - Metric

Guhring Jobber Drills Steam Tempered HSS

Suitable for drilling steel, cast steel, alloyed and unalloyed, grey cast iron, spheroidal iron, sintered powder metal, German silver and graphite. Manufactured to BS328/DIN338RN.

Black Finish (W-Finish)
This is the most common surface finish and is the result of a steam tempering operation in which steam is passed over the product during a controlled tempering cycle, producing a black oxide layer. Black tools are generally recommended for ferrous applications where the oxide layer aids chip flow, helps to dissipate heat by retaining some coolant on the tool surface and also helps to prevent the tool from staining.

Series 205

Guhring NC Spotting Drills HSS

Special drill for accurate and fast slotting on NC machines, jig drills and other capital-intensive boring machines. For countersinking and chamfering of tapping holes in one operation. N.B. Only suitable for shallow depth drilling. Type N: Guhring standard, overall lengths to DIN1897. 90 Point.

For all dimensional specifications please refer to our catalogue.

Series 557 - 90 Degree

Guhring Long Series Drills HSS-Co 8%

High heat resistance with wide chip space for use with drill bushings. For drilling alloyed and unalloyed steels and castings with a tensile strength over 800N/mm2. Type N. Manufactured to DIN340.

For all dimensional specifications please refer to our catalogue.

Series 317 - Metric

Guhring Stub Drills HSS

Ideally suited for portable drill applications where the shorter flute and stub length offer the extra rigidity normally associated with fixed drilling. Manufactured to BS328:Part 1:1986/DIN1897RN.

Series 223

Guhring Stub Drills Carbide SL

Carbide drills deliver a quantum leap in high speed holemaking performance and tool life that manufacturers have been asking for. Carbide tooling provides faster cutting rates, longer tool life, better positional and dimensional accuracy and improved surface finish. Short cycle times and tighter tolerances translate into maximum machine utilizations, better part quality and optimum holemaking cost savings.
