Straight Flute Hand Tap M12-1.25

The Cleveland C54677 is a straight flute hand tap designed for cutting M12 x 1.25 metric threads. It suits mechanics and fabricators who need to create or repair internal threads in metal components using hand tools.

High-speed steel construction with bright finish

Made from high-speed steel with an uncoated bright finish, the tap resists wear during manual threading operations. The 85.72 mm overall length and 42.07 mm thread length provide reach for deeper holes, while the D5 thread limit targets a 6H class of fit.

Bottoming chamfer for blind-hole threading

The bottoming chamfer allows threading close to the bottom of blind holes where a taper or plug tap cannot reach. A 75 percent thread drill size of 10.78 mm is required to prepare the hole correctly before tapping.
