M12 x 1.75 metric thread tap
The Cleveland C54691 is a straight-flute hand tap cut for an M12 x 1.75 metric thread. It is made from high-speed steel with a bright, uncoated finish and a right-hand thread direction. The thread limit is D6 for a 6H class of fit, suited to general-purpose threading work.
Bottoming chamfer for through or blind holes
A bottoming chamfer lets the tap cut threads close to the bottom of a blind hole or run through a through-hole. The thread length is 42.07 mm within an overall length of 85.72 mm. A 10.30 mm drill size prepares the hole for approximately 75 percent thread engagement.
D6 limit matches 6H tolerance class
The D6 limit provides the correct oversize for a standard 6H internal thread, giving reliable pitch diameter control in steel and similar materials. The uncoated high-speed steel edge works well in manual or machine tapping where coolant or lubricant is used. It is not designed for high-volume production runs that demand coated or spiral-point tooling.

Questions about this item
What thread limit does the Cleveland C54691 tap reach before it starts to bind in deeper holes?
The tap is manufactured to a D6 thread limit, which controls the pitch-diameter tolerance for a 6H class of fit.
Does the high-speed steel hold its edge without overheating during a full day of hand tapping?
High-speed steel construction resists heat build-up during manual use, and the bright uncoated finish reduces friction in steel and non-ferrous metals.
What size drill bit must I already have to prepare the correct 75 percent thread hole?
A 10.30 mm drill bit is required to produce the recommended 75 percent thread depth for M12 x 1.75 tapping.
