Dormer Stub Drills HSS TiN Tip Coated

Designed for increased productivity and tool life compared to standard stub drills. TiN coating has been applied to 35%-50% of the flute length (dependent on drill diameter) to keep cost down and lower the cost per hole. The 135 split point is advantageous for the pre-drilling of rivets and for drilling in sheet metal. Suitable for drilling alloy steel, carbon steels, cast iron, titanium and aluminium. Manufactured to DIN1897, ANSI.

Series A022 Stub Drill HSS TiN Tip Coated - Metric

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.

Number & Letter Gauge Drills:
Gauge drills are still in common use in the U.S. In the past, they were popular elsewhere, but now have been largely discarded in favour of metric sizes. When using a gauge rather than a standard measurement of size the user has to refer to a table of gauge sizes. For example, to drill a hole which is 10 thou (thousandth of an inch .0010) bigger than a 1/8 inch bolt, the user must first work out that 1/8 inch is 125 thou, so the hole size needed is 135 thou, and then must look up in a reference book which gauge drill bit is closest to this diameter - a number 29. Number gauge sizes are similar or equivalent in some respects to, but different from, American wire gauge. Number gauge is usually used from size 80 (the smallest) to size 1 (the largest) followed by letter gauge size A (the smallest) to size Z (the largest). Number gauge is actually defined down to size 97, but these smaller sizes are rarely encountered. It happens that as the technology for making small drill bits and drilling small holes has become more available, metric drills have become the norm.
