RUKO HGB-DIN352-HSS-60°-1 Macho de roscar manual de desbaste e acabamento métrico, M1 x 0,25 mm, HSS, DIN 352, 6H, 3 ranhuras, branco

Threading at M1 x 0.25 mm demands precision, and this RUKO taper tap delivers with a 6H tolerance class and 60° thread angle. The HSS construction with bright finish handles unalloyed steels, cast iron, and non-ferrous metals, while the taper lead starts threads cleanly in through or blind holes.

Overview

The RUKO HGB-DIN352-HSS-60°-1 is a metric machine tap manufactured to DIN 352. It features a nominal diameter of 1 mm with a 0.25 mm pitch, three straight flutes, and a right-hand cutting direction. The taper lead (Vorschneider) reduces cutting forces at thread entry, making it suitable for manual threading applications.

What stands out

• Precision 6H tolerance class for reliable thread fit
• High-speed steel (HSS) for durability across common materials
• Taper lead for easier starting and reduced breakage risk
• Compact overall length of 38 mm for access in tight spaces
