Product details : DOR EX21 5-40 HSS-XS1 ST SPECTRUM UNC SP FLT DIN 2184-1


HSS (Vanadium content) taps for machining threads in through holes in most materials, Manufactured from premium grade powder metallurgy steel with increased Vanadium content for unbeatable toughness, edge strength & wear resistance

Strengths

Powdered metal substrate offers superior performance that approaches that of solid carbide tools but with the toughness and shock-resistance of high-speed steel
Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge
When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
Round with square end shank
Blind hole

Applications

Multi-Application
Semi-Bottoming
