EX-SUS-POT Spiral Pointed Tap for Stainless Steels
Workpiece material (ISO)
M · StainlessN · Non-ferrous
HSSE spiral pointed tap with a Steam Oxide surface treatment for through-hole tapping in stainless steel, copper, and thermoplastics — the spiral point pushes chips forward while the treatment reduces galling on gummy materials. Offered in Metric (M), Unified (U/UNC), and Whitworth (W) thread types, plus a long-shank (EX-LT-SUS-POT) variant.
Features & uses
Engineered for performance
1
Through-hole spiral point
The spiral-point flute pushes chips forward through the hole ahead of the tap, avoiding the chip-packing common to through-hole tapping.
2
Stainless / copper / thermoplastic
Suited to tapping through holes in stainless steel, copper, and thermoplastics.
3
Steam Oxide treatment
A Steam Oxide surface treatment reduces friction and adhesion on gummy, non-free-machining materials.
4
Long-shank variant available
Also offered as EX-LT-SUS-POT, a long-shank version for extended reach.
