Product Features
CARBIDE AL+SP guarantees consistent tapping even in medium-high speed cutting area, in forged workpieces of light alloys such as aluminum die castings and
aluminum castings.
Featuring an optimized cutting edge design, AL+SP does not produce burrs in minor diameter which usually occours during tapping light alloys. AL+SP
ensure reliability and high quality internal threads.
