Product Description

YG-1 TB264 HSS-E UNC spiral-point machine taps use a thick web for through-hole threading operations. Designed for through holes, this gun-point tap produces unified coarse UNC internal threads. The thick web supports use at higher cutting speeds than other taps. TB264 is recommended for stainless steel, with suitability also indicated for selected steel grades and materials. Available sizes run from #6-32 UNC to 7/8-9 UNC for common coarse-thread applications. Smaller sizes through 3/8 inch follow DIN 371, while larger sizes follow DIN 376. Six or four flutes are specified by size, providing an established range for machine tapping in production environments.
