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.

Dormer 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.
