Widia Gtd Spiral Flute Tap 7/16"-14
The Widia Gtd VTSFT-TC5160 is a spiral flute tap designed for creating internal threads in metal components. It suits machinists and maintenance technicians who require reliable thread production in through-hole or blind-hole applications. The UNJC thread form meets controlled-radius root specifications for high-stress fastening. This tool targets professional workshops handling aerospace or automotive repair work.
High-speed steel construction
High-speed steel construction provides wear resistance during repeated threading operations. The black oxide surface treatment helps retain cutting lubricant and reduces galling on the workpiece. A 7/8 in thread length and 3 5/32 in overall length allow access to standard-depth holes. Right-hand thread direction matches common fastener requirements for assembly tasks.
75 percent thread drill size U and H5 thread limit
The H5 thread limit and Class of Fit 2B ensure consistent thread geometry for gauge verification. A 75 percent thread drill size U guides drill selection without separate lookup tables. Three flutes improve chip evacuation compared to two-flute designs, reducing tap breakage risk. California Proposition 65 notice applies due to chemical content in the coating.
