Cleveland C54689 M12 Hand Tap

The Cleveland C54689 is a straight flute hand tap designed to cut M12x1.75 metric threads in through holes or blind holes with adequate clearance. It suits maintenance technicians and machinists who need to create new internal threads or repair damaged ones using hand-operated or light machine tapping.

High Speed Steel Construction

Made from uncoated high speed steel, the tap resists wear during manual threading operations on mild steel and similar materials. The bright finish reduces galling without adding coating thickness, while the 42.07 mm thread length provides sufficient engagement depth for standard fastener applications.

Replaces Worn Or Incorrect Taps

This tap replaces a dull, chipped, or wrong-pitch tap when thread quality degrades or when the required M12x1.75 size is not already in the toolkit. The jump is worth it when the existing tool produces loose threads, requires excessive force, or cannot start cleanly in the 10.30 mm drill hole.

Questions about this item

How do you install the Cleveland C54689 M12x1.75 straight flute tap and what step is often missed?

Use a 10.30 mm drill for the 75 percent thread hole, then run the tap by hand with a tap wrench; the step often missed is applying cutting fluid and reversing frequently to break chips in the 42.07 mm thread length.

What maintenance or replacement will the Cleveland C54689 tap need over time?

The high-speed steel cutting edges dull with use; replace the tap when threads feel rough or the D6 limit no longer produces a clean 6H fit.

What limit appears first during sustained tapping with the Cleveland C54689?

Chip evacuation in the straight flutes becomes the limiting factor in deep holes, especially beyond the 42.07 mm thread length, causing torque rise and tap breakage risk.
