Dormer Drill Bit HSS 25/64″

TiN-Tip Performance The Titanium Nitride coating at the point reduces friction and dissipates heat, allowing for increased cutting speeds and a service life significantly longer than standard HSS bits.

Precision Self-Centering Equipped with a 118° split point geometry, this bit eliminates the need for a center punch. It bites into the material immediately, ensuring the hole remains perfectly on-center.

Superior Chip Evacuation The specialized flute design is engineered to lift and remove swarf rapidly. This prevents clogging, reduces heat buildup, and ensures a cleaner finish inside the hole.

Industrial-Grade Versatility Specifically designed to drill through a wide range of materials, including alloy and non-alloy steels, 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 fluids, ensuring the bit stays lubricated and cool during heavy-duty tasks.

Compact Compatibility At 9.92mm, this is one of the largest sizes that can still fit into a standard 10mm (3/8″) chuck, making it highly versatile for both portable drills and stationary presses.
