STEP DRILL BIT SET ( 3 PCS )

3-Piece Professional High-Speed Stepped Drill Bit Set

Stop hauling around a heavy box of dozens of individual drill bits. This premium 3-piece Step Drill Bit Set features a progressive, step-milled conical profile that lets you drill clean, perfectly round, burr-free holes across dozens of distinct millimeter increments through sheet metals, aluminum plates, PVC conduits, and plexiglass smoothly using a single bit.

Key Features:

Dual-Flute Spiral Layout: Clears out metal shavings rapidly, lowering friction heat and preventing tool binding for lightning-fast drilling.

Laser-Etched Scale Markings: Permanent, high-contrast size indices inside each step let you read hole dimensions easily while the bit is spinning.

Tri-Flat Non-Slip Shank: Features a custom machined 3-sided base that locks securely into standard drill chucks, completely preventing slipping under high torque loads.
