Beta Tools 412/4,00 Short HSS Drill Bit, 4.00mm

Brand: Beta Tools

If you work with metric hardware, chances are sooner or later you will need to drill and tap a metric hole. But metric drill bits can be hard to find -- so much so that many tap drill charts list the "nearest SAE size" drill bit! These metric drill bits from Beta Tools will do the job better and with less stress.

The 412 Series metric bits are "screw machine" length (5/8 the length of "jobber" bits) to minimize breakage due to flexing. High-Speed Steel (HSS) construction with a bright finish. HSS material is recommended for use on mild steel, aluminum, and other soft materials. The 118° point requires a center punch to prevent walking.

This 412/4,00 bit measures 4.00mm OD (Ø) with a straight shank (shank OD matches drill size). Measures 75mm Long overall (L) with 43mm long flutes (L1). Sold individually.
