Dormer Drill Bit HSS 3/32″

TiN-Tip Thermal Protection The Titanium Nitride coating at the point reduces friction and dissipates heat, allowing for faster feed rates and a service life significantly longer than standard uncoated HSS bits.

Precise 118° Split Point Despite its small size, this bit features a self-centering split point. It bites into the material immediately, eliminating “skating” and the need for a center punch, which is critical when working on small components.

Optimized Swarf Evacuation The specialized flute geometry is designed to lift and remove chips rapidly. This prevents clogging, a primary cause of bit breakage in diameters under 1/8″.

Steam Tempered Finish The body features a steam-tempered (blue) finish that improves the retention of cutting lubricants, ensuring a smoother cut and reducing the risk of the bit seizing in the workpiece.

Wide Material Application Highly effective for drilling into a wide variety of materials, including alloyed and non-alloyed steels, cast iron, and non-ferrous metals like aluminum and brass.

Standard Compatibility With a diameter of 2.38mm, this straight-shank bit is compatible with all standard drill chucks and precision rotary tool collets.
