Dormer Drill Bit HSS 5/64″

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, ensuring pinpoint accuracy on small workpieces.

Efficient Chip Removal Features optimized flute geometry designed to lift and evacuate swarf rapidly. This prevents clogging and heat buildup, which is vital for preventing breakage in very thin bits.

Broad Material Versatility Engineered to perform exceptionally well across a wide variety of materials, including alloyed steel, carbon steel, cast iron, and non-ferrous metals like aluminum or brass.

Steam Tempered Finish The body features a steam-tempered (blue) finish that improves the retention of cutting lubricants, ensuring the bit remains cool and the internal hole finish stays smooth.

Universal Shank Fit With a diameter of 1.98mm, this bit is compatible with all standard drill chucks and precision collets used in rotary tools and bench drills.
