SKU CH-3KY3-5Z7AK

  • TypeHole, Drill, Bore & Wire Gauges
  • 3/4"-10 UNC thread cuts standard coarse holes
  • Taper lead starts threads easily in new holes
  • Four straight flutes clear chips during hand tapping
  • 25 in overall length fits common tap wrenches
  • Bright carbon steel resists galling in mild steel

3/4"-10 UNC Taper Tap

This straight-flute hand tap cuts unified coarse threads in a 3/4 inch diameter with 10 threads per inch. The taper chamfer eases starting in through-holes or blind holes with adequate clearance. Four flutes provide chip space and cutting stability in general-purpose materials. The bright, uncoated carbon steel body suits hand tapping and light machine work.

Suited for maintenance and repair threading

Mechanics and fabricators who need to cut new internal threads or chase damaged ones in steel, cast iron or similar metals will find the taper lead forgiving. The tool is not for high-volume production runs, for materials that demand coated or powder-metal taps, or for bottoming operations where a plug or bottoming chamfer is required.

Fits standard tap wrenches and holders

The 4.25 inch overall length and 2 inch thread length work with common adjustable tap wrenches and T-handle drivers. Square shank engagement transmits torque without slipping. No special holders, coolant systems or powered drivers are needed, freeing the operator to use basic shop equipment already on hand.

Questions about this item

What tap wrench size fits the 4.25 in overall length of this Westward tap?

Choose a tap wrench with a jaw capacity that accommodates the 4.25 in overall length and the shank diameter of a 3/4"-10 UNC tap for secure hand operation.

Can I start threads with this taper tap in a hole previously drilled for an older 3/4"-10 tap?

Yes, the taper lead on this 3/4"-10 UNC tap is designed to start threads easily in an existing correctly sized hole, even if the hole was drilled for an older tap.

How do I verify the 2 in thread length is cutting to the correct 1B class of fit?

After tapping, check the internal threads with a 3/4"-10 UNC 1B thread plug gauge; the GO member should enter fully while the NO-GO member should not.
