NO NAME M20 Machine Tap DIN 352 HSS 6H Hand Tap for Metric Coarse Threads

Cutting clean M20 metric coarse threads by hand demands a tap that stays sharp, aligns true, and clears chips without jamming. This NO NAME hand tap follows DIN 352 and is ground from high-speed steel to a 6H tolerance, so the resulting threads accept standard M20 bolts with a precise, durable fit. Unlike sets that force you to buy three taps, this single tap is ready for through-hole and blind-hole work where a full thread profile is needed in one pass.

Highlights

• M20 × 2.5 mm metric coarse thread, right-hand cut
• DIN 352 machine tap with straight flutes for manual or low-speed machine use
• HSS bright finish for wear resistance up to 900 N/mm²
• Square drive shank for a secure tap wrench grip
• 6H tolerance class for standard metric nut and bolt fit

In daily use

The 110 mm overall length and 38 mm thread length give enough reach for most repair and fabrication jobs. The square drive measures 12.5 mm across flats, matching common tap wrenches. Straight flutes push chips forward, which works well in through holes, while careful backing off clears blind holes. The uncoated HSS surface cuts cleanly in steel, cast iron, and non-ferrous metals without built-up edge.
