Key Features & Benefits
- M2 High-Speed Steel construction — long edge life cutting steel up to 1000 N/mm² without premature dulling.
- Ground from solid — Sutton’s signature ground-from-solid process delivers concentric flutes and consistent thread form.
- ISO529 straight flute — industry-standard geometry suits both hand tapping and powered use in most engineering metals.
- 6H tolerance class — produces a class-fit thread that mates accurately with standard fasteners.
- Australian made — manufactured at Sutton’s Thomastown plant — same family business that has supplied Australian trades since 1917.
When to Use This HSS Hand Tap
Use this tap when cutting accurate threads in tougher engineering metals — mild and tool steels, stainless, cast iron, brass, aluminium and bronze — where carbon-steel taps would dull quickly. The taper lead-in makes it the natural starter tap; follow with the intermediate (second) and bottoming (plug) tap from the same series for blind holes. This particular variant (T4150483) cuts a #10-24 UNC Intermediate thread.
Pro Tip: Use a quality cutting fluid (Sutton recommends sulphurised oil for steels and a wax stick or kerosene for aluminium) and back the tap off a quarter-turn every one to two full turns to break the chip — this prevents heat build-up and stops the flutes packing up in deeper holes.
