Cleveland C54167 Straight Flute Hand Tap M3-0.50 3-Piece Kit

SKU CH-TARC-PSBPZ

Three-piece M3-0.50 straight-flute hand tap kit in high-speed steel includes taper, plug and bottoming taps

  • M3 metric threading for precise fastener fit
  • Three-piece set provides taper, plug and bottoming taps
  • High-speed steel construction resists wear during hand threading
  • Bright uncoated finish suits general-purpose tapping tasks
  • 5/8 in thread length matches standard M3-0.50 specifications

Three-Piece M3 Tap Kit

This Cleveland C54167 kit provides three straight-flute hand taps for cutting M3 by 0.50 metric threads. The set includes taper, plug and bottoming styles so a single kit covers the full threading operation. It is aimed at mechanics and hobbyists who need to create or repair internal threads in metal by hand.

Capacity and Headroom

Each tap has a thread length of 5/8 in and an overall length of 1 15/16 in, made from bright high-speed steel. The D3 limit and 6H class of fit suit general-purpose work in ferrous and non-ferrous materials. The kit runs out when a through-hole exceeds the thread length or when machine-tapping speed and chip evacuation are required.

Practical Limits of Hand Tapping

The straight-flute design relies on manual reversal to break chips, so deep blind holes can trap swarf and damage the tap. A 2.50 mm drill produces the 75 percent thread engagement specified for this size. The right-hand, three-flute geometry offers no advantage for left-hand threads, hardened steels or high-volume production where spiral-point or spiral-flute tools are standard.

Questions about this item

Will the M3-0.50 tap set work with a 2.50 mm drill bit I already own for 75 percent thread engagement?

Yes, the kit specifies a 75 percent thread drill size of 2.50 mm, so your existing bit matches the recommended size for proper thread depth.

How can I confirm the taps are cutting to the correct 6H class of fit after setup?

Use an M3-0.50 6H go/no-go thread gauge on the finished hole; the go gauge should pass fully while the no-go gauge stops within the specified turns.

Does the 3-piece kit include bottoming, plug, and taper taps, or must I buy any of them separately?

The kit contains all three taps — bottoming, plug, and taper — so no additional tap purchases are required for standard through or blind holes.
