Sherwood Spotting Drills HSS-E
These specially designed drills produce accurate and true positional hole starts for follow-up drills. They provide exceptional alignment accuracy, achieved due to short flute and overall lengths and no body clearance. This very short design allows chucking very close to the point so that they will produce a true start or center. Traditional twist drill bits may tend to wander when started on an unprepared surface. Once a bit wanders off-course it is difficult to bring it back on center. A spot drill bit will provide a far better starting point as it is short and has a reduced tendency to wander. For accurate and fast spotting on NC machines, jig drills and other capital-intensive boring machines. Also suitable for countersinking and chamfering of tapping holes in one operation.
90 point angle - Offers hole chamfering and spotting with one tool.
120 point angle - Specifically for spotting and closely matches a typical drill point. The cutting edges of the following drill will engage easily for perfect hole location.

●产品描述:
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.
