Dormer Drill Bit HSS 15/64″

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

Precision Self-Centering Equipped with a 118° split point geometry, the bit bites into the material immediately. This eliminates “walking” or “skating” and removes the need for a center punch in most applications.

Efficient Chip Removal Features optimized flute geometry designed to lift and evacuate swarf rapidly. This prevents clogging and heat buildup, ensuring a smooth finish on the internal hole walls.

Wide Material Versatility Engineered to perform exceptionally well across a broad spectrum of materials, including alloyed steel, carbon steel, cast iron, and non-ferrous metals like aluminum.

Steam Tempered Finish The body features a steam-tempered (blue) finish that improves the retention of cutting lubricants, ensuring the bit remains cool and lubricated during continuous drilling.

Universal Shank Fit With a diameter of 5.95mm, this bit is fully compatible with all standard 10mm (3/8″) and 13mm (1/2″) drill chucks, as well as smaller hobbyist drills.
