14-Piece Titanium Twist Drill Bit Set with 1/4-Inch Hex Shanks and Split Points for Impact Drivers

A 14-piece titanium-coated twist drill bit set fits compatible 1/4-inch hex impact drivers for fast changes across metal, wood and plastic tasks. Makita Impact Gold B-65399 uses 135-degree split-point geometry to start holes faster and reduce walking.

The titanium nitride coating is listed to last 2.5 times longer than comparable non-coated bits, while the impact-rated hex shanks suit compatible drivers sold separately. Sizes include 1/16, 5/64, 3/32, 7/64, two 1/8-inch bits, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8 and 1/2 inch. The assortment is intended for ferrous and non-ferrous metal, cast iron, stainless steel, wood and plastic when the selected tool and speed are appropriate. Confirm the impact driver accepts 1/4-inch hex accessories, clamp the workpiece and wear suitable eye protection. Reduce pressure as the bit exits material, allow hot bits to cool and return all 14 clean dry pieces to storage.
