VALYRIANTOOL 60PCS Micro Drill Bits Set HSS Black Gold 10 per size

Micro drill bit set for mixed materials

The VALYRIANTOOL 60PCS Micro Drill Bits Set supplies 60 high-speed steel twist bits in six fractional sizes from 3/64" to 1/8". Ten pieces per size give workshops and hobbyists immediate replacements for small-diameter drilling in mild steel, copper, aluminum, zinc alloy, wood and plastic. The jobber-length geometry keeps the bit rigid under pressure while maintaining clearance from the workpiece surface.

Fits standard drill chucks without adapters

Each bit uses a straight shank that seats directly in common three-jaw chucks, so no special collets or sleeves are required. The flatted shank prevents slippage during high-torque starts, and the compact plastic case organises all 60 pieces by diameter for quick selection. The assortment covers pilot holes, clearance holes and light tapping preparation across the listed materials.

Black gold coating reduces heat and wear

The premium M2 high-speed steel with black gold finish adds lubricity that stops metal chips from adhering to the flutes. Fully ground spiral grooves evacuate swarf quickly, lowering friction and temperature during continuous use. The 135-degree split point centres itself without a centre punch, cutting with less feed force and producing cleaner holes in both metal and wood.
