M12-1.75 tap set for manual threading
This three-piece hand tap set cuts metric M12 threads with a 1.75 mm pitch using high-speed steel. It includes taper, plug and bottoming taps so you can start, progress and finish a thread by hand. The bright uncoated finish suits general-purpose work in steel and non-ferrous metals. Right-hand threads are produced to a 6H class of fit with a D6 limit.
1 21/32 in thread length and 3 3/8 in overall length
Each tap provides a thread length of 1 21/32 in within an overall length of 3 3/8 in, giving enough reach for through-holes and moderate blind-hole depths. Four flutes help evacuate chips during hand operation. The set handles most maintenance and repair tasks but will run out of reach in very deep holes or when machine rigidity is required for high-volume production.
Bright uncoated HSS with no added coatings
The taps ship without surface treatments, so they rely on cutting fluid and proper technique for tool life. No lubricants, guides or cases are bundled, meaning you supply the tapping fluid and alignment method. Buyers who need coated taps for longer life in abrasive alloys or who want a storage case will need to source those separately.

Questions about this item
Will the M12-1.75 thread size and D6 limit match the nuts I already use on older metric equipment?
The set cuts a standard metric M12 thread with 1.75 pitch to a 6H class of fit using a D6 limit, so it aligns with common metric fasteners.
How can I check the 1 21/32 in thread length and 3 3/8 in overall length are cutting correctly after setup?
Measure the threaded portion against the 1 21/32 in spec and the full tap against the 3 3/8 in spec; clean, gauge-fitting threads confirm proper operation.
Does the three-piece HSS set include any handles, lubricant or drill bits, or must I buy them separately?
The box contains only the taper, plug and bottoming taps; handles, cutting fluid and the correct tap-drill bit are sold separately.
