Alpha Onsite+ Impact Step Tip Drill Bit - Spiral Flute (C9STQRM Series)
The Alpha Onsite+ C9STQRM Series brings speed and convenience to step drilling, designed specifically for the modern tradesperson using cordless impact drivers. Featuring a unique patented "Step Tip" design, this bit bites instantly into the material, completely eliminating the need to drill a pilot hole first. The dual spiral flutes clear chips rapidly, allowing for 3x faster cutting than standard straight-flute bits, while the premium AlTiN coating ensures it survives the high heat of drilling stainless steel and tough alloys.
Features:
Patented Step Tip Design: The innovative tip geometry allows the bit to self-start immediately without "walking," eliminating the need for centre punching or pre-drilling a pilot hole.
Dual Spiral Flutes: Engineered with two spiral cutting edges that evacuate chips far more efficiently than straight flutes, resulting in 3x faster drilling speeds and clean, burr-free holes.
Impact Driver Ready: Features a 1/4" Quick-Change hex shank that snaps directly into impact drivers and cordless drills, preventing the bit from spinning in the chuck under high torque.
AlTiN Coating: Coated with Aluminium Titanium Nitride (AlTiN) to provide extreme heat resistance and surface hardness, significantly extending the cutting life when working with stainless steel.
Versatile Material Application: The optimized cutting geometry makes this bit ideal for a wide range of materials, including sheet steel, stainless steel, wood, and rigid plastics.
