21-piece HSS drill bit set

This Chicago-Latrobe 41799 set contains 21 jobber-length drill bits made from high-speed steel with a titanium nitride finish. Each bit features a 135-degree point angle designed for efficient starting and reduced walking on metal surfaces. The assortment covers a range of diameters for general-purpose drilling tasks in workshop or maintenance environments.

Suited for metal drilling in maintenance

Mechanics and fabricators who need a ready supply of replacement bits for ferrous and non-ferrous metalwork will find this assortment practical. Buyers who require specialised bits for masonry, wood spade drilling or large-diameter hole cutting should look at dedicated sets for those materials. The high-speed steel construction is not intended for continuous high-heat production drilling in hardened alloys.
