General description Much Harder - M35 HSS is much harder than HSS 4241, making it suitable for drilling stainless steel plates, quenching steel plates, iron plates, aluminum, and wood. The drill bit set features a triangular shank that fits securely into power tool chucks, eliminating slippage. Its two-flute design removes chips faster and allows particles to escape easily, while the split tip increases drilling speed. Additionally, it can automatically deburr holes while drilling, keeping the bit clean. Technical specifications Material: M35 HSS Size range: 4-32mm Number of sizes: 15 (4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, 32mm) Usage Water can be used to cool the drill bit during operation, extending its lifespan.
