Alpha 25 Piece Cobalt Metric Tuffbox Pro Drill Set 1-13mm - SM25COTP
The Alpha SM25COTP 25 Piece Cobalt Drill Set is the professional's choice for drilling extreme materials that destroy standard bits. Engineered from premium M42 High-Speed Steel with 8% Cobalt content, these bits are specifically designed to withstand the intense heat generated when drilling stainless steel, cast iron, and high-tensile alloys. Housed in the rugged "Tuffbox Pro" case, this set ensures your high-performance bits are protected from site damage and moisture, keeping them sharp and ready for the toughest tasks.
Features:
8% Cobalt M42 Construction: Manufactured with a heavy-duty 8% Cobalt alloy which provides superior red-hardness, allowing the bit to maintain its cutting edge even at the extreme temperatures generated by drilling stainless steel.
135° Split Point: Features a precision self-centering split point that bites into the material immediately, preventing the bit from "walking" across the surface and eliminating the need for a centre punch.
Tuffbox Pro Storage: Supplied in Alpha's signature impact-resistant case with a secure locking catch and rubberized corners, ensuring your investment is protected from drops, dust, and harsh job site conditions.
Fully Ground Flutes: Precision ground from solid stock (rather than roll-forged) to ensure perfect concentricity and rapid chip ejection, resulting in cleaner, more accurate holes.
Feeds & Speeds Chart: Includes a convenient reference chart inside the case lid, helping you select the optimal RPM for different materials to maximize the lifespan of your drill bits.
