M10-1.00 Plug Tap for Metric Threads

This Greenfield Threading hand tap cuts internal threads in a single pass using a straight-flute design. It targets machinists and maintenance technicians who need a reliable M10 × 1.00 plug tap for general-purpose threading work. The D11 thread limit and 6H class of fit suit standard metric fastening requirements.

Sustained Cutting in High-Speed Steel

High-speed steel construction with a black-oxide finish resists wear during repeated hand-tapping cycles. The spiral-point geometry pushes chips ahead of the flutes, reducing torque buildup and allowing smoother operation through the full 31.75 mm thread length. Three flutes provide balanced chip clearance for consistent results in through-hole applications.

Drill Size 9.00 mm Determines Fit

A 75-per-cent thread engagement requires a precise 9.00 mm tap drill; deviating from this size will produce oversize or undersize threads that fall outside the 6H tolerance. The 74.63 mm overall length and right-hand cut are fixed by the 313572 specification, so verify the drill diameter before starting the job.

Questions about this item

Does the M10x1.00 tap generate noticeable heat during extended hand-threading sessions?

High-speed steel construction and black-oxide coating dissipate cutting heat efficiently, keeping the 74.63 mm tool comfortable for continuous use.

What drill bit must I already own to prepare the correct 75-percent thread hole?

A 9.00 mm drill bit is required to produce the proper tap-drill size before engaging the M10x1.00 thread.

Will this D11-limit tap cut cleanly in older mild-steel workpieces I keep in the shop?

The 6H class-of-fit and three-flute geometry are suited for general-purpose materials, including older mild-steel stock.
