Metallics HSSCN35E Drill Bit HD Cobalt St 135d SplPt #35 2-5/8" YLW (1pc)

Yes. A #35 wire gauge bit measures 0.110 inch, which is the standard tap drill size for 6-32 threads, so the Metallics HSSCN35E is the bit electricians reach for when tapping 6-32 for ground screws and device mounting. For a clearance hole rather than a tapped hole, you want a larger bit.

That is what cobalt is for. The HSSCN35E is a heavy duty cobalt high speed steel bit, and cobalt alloy holds its edge at the higher temperatures you generate in stainless, hardened steel, and heavy strut or enclosure steel, where plain HSS dulls or burns. For mild steel, aluminum, and plastic it works fine too, just with more cutting life than you need.

It lets you start a hole without center punching. A 135 degree split point is flatter than a standard 118 degree tip and the split relieves the web, so the bit bites immediately instead of walking across a hard surface, such as an enclosure wall or a steel beam flange. It also pushes chips out faster, which matters when you are drilling overhead.

Less than the 2-5/8 inches of total length. That figure is the overall length of the HSSCN35E, which includes the straight shank held in the chuck, so usable flute depth is shorter. For through holes in sheet metal, enclosures, strut, and angle iron it is plenty; for anything deeper, step up to a longer jobber or aircraft length bit in the same #35 size.

One bit per pouch. The HSSCN35E ships as a single piece in a pouch, not as part of an index or set, so if you are stocking a van or a shop drawer you order each size separately by its own part number.
