-Made from high strength and durable chrome vanadium steel. IRWIN® Hex and Torx keys have a black oxide surface and are specially ground for improved grip.
- For aggressive grinding with maximum stock removal rate on hard materials which do not conduct heat well. - Consistently high performance due to self-sharpening ceramic oxide grain. - Active grinding additives in the coating substantially improve the stock removal rate, prevent clogging and result in cooler grinding. - Abrasive: Ceramic oxide grain CO-COOL.
ADVANTAGES - Permanent elasticity and excellent adhesion to all construction materials; - Excellent mechanical properties; - Movement accommodation up to 25%; - Resistant to atmospheric effects, U.V. and ageing; - Resistant to various chemicals; - Does not cause corrosion; - Does not run in vertical joints; - Prevents the formation of mold on the silicone due to the special mixture; - Complies with the ISO 11 600 standard.
Internal hex drive with a collar-thrust spring. Bits are easy to insert, lock securely in position and can be removed just as easily; even hex bits with a wide groove (Type E, DIN 3126/ISO 1173).
