13-Piece HSS Twist Drill Bit Set, High-Speed Steel Hex Bits with Titanium Coating, 1.5mm - 6.5mm

Set of 13 professional drill bits: 1.5 mm, 2 mm, 2.5 mm, 3.2 mm, 3.5 mm (62.6 cm), 4 mm (5/32"), 4.5 mm (11/64"), 4.8 mm (3/16"), 5 mm (13/64"), 5.5 mm (7/32"), 6 mm (15/64"), 6.5 mm (1/64"), 6.5 mm (1/32") (10.2 mm)

High-quality material: The drill bits are made of high-speed steel with a titanium coating, which offers superior heat resistance and a long service life.

Quick drill bit replacement: The 6.35 mm hex shank is compatible with all power tools, making it easier, more convenient, and safer to use.

Smooth drilling: Designed with a 135° cutting angle, it can automatically center and penetrate quickly with minimal pressure. The threaded chip flutes can remove chips and debris more quickly.

Long service life and durability thanks to the high-quality high-speed steel material.

Equipped with a 6.35 mm hex shank for quick and easy bit changes.

M35 Cobalt high-speed steel for drilling steel, stainless steel, hard metal, and iron. The 135-degree split point starts drilling immediately with less force and eliminates the "stepping" on the work surface.

Solid and durable.

Classic high-speed steel construction with titanium coating for added capacity and durability.

Quick and precise change.

The 135° split point provides a fast cut with a 0.6 cm gap for quick changes. The sharp edge of the hexagonal shank is hardened and honed for fast, precise cutting while preventing chipping and shedding. Rapid particle removal. The fully ground spiral groove design directs chips and debris away from the drill bit, reducing friction and heat for a faster, cooler drilling process. Applicable materials: The multi-size drill bit set is suitable for metal (steel plate, aluminum plate, iron plate), wood, and PVC (not suitable for walls, ceramic tiles, etc.). Keep vertical. When drilling, try to keep the drill bit perpendicular to the object. Control speed and pressure. When using electric drills, it is recommended to use them at a low speed and drilling pressure. The thicker the drill bits, the slower the speed and pressure. Keep cool. Friction will build up heat between the bits and the workpiece. Be careful of the heat; add water or coolant if necessary. Keep out of reach of children. For children's safety, please use under adult supervision.
