A steel machine tap with a TiCN coating, offered mainly as gun nose (spiral point) through M3-M20, plus a spiral flute M3 variant for blind holes.Key specs Material: steel Coating: TiCN Thread standard/pitch: M3 x 0.5 Compatibility / fitmentRequires a tapping machine/CNC with the matching thread size and pitch — confirm drive/thread spec.Application / use caseTiCN is harder and more wear-resistant than TiN or TiNi, so this range holds a sharp edge and resists galling when tapping stainless steel and tougher alloy steels that would quickly dull an uncoated or lighter-coated tap. The gun nose sizes push chips ahead of the tap for efficient through-hole work, while the M3 spiral flute variant instead draws chips back up the flutes and out of the hole, making it the better choice when that thread is blind rather than through.
