Cleveland C54857 Straight Flute Hand Tap

The Cleveland C54857 is a straight flute hand tap designed for creating M20x1.50 metric threads. It is intended for manual threading operations in maintenance, repair and light production environments where machine tapping is not available.

Plug chamfer and bright finish

The plug chamfer provides a moderate lead-in that starts threads easily in through-holes and blind holes with adequate depth. The bright uncoated high-speed steel surface suits general-purpose cutting in steel and non-ferrous materials without specialised coatings.

For machinists cutting M20x1.50 threads by hand

This tap suits technicians who need a single M20x1.50 plug tap for occasional hand-threading tasks. It is not for high-volume production runs requiring coated or spiral-point taps, nor for users who need a complete taper-plug-bottoming set or different thread pitches.

Questions about this item

Will the M20x1.50 tap need resharpening after cutting several holes?

The high-speed steel cutting edges can be resharpened when they dull, extending the tap's service life.

What limits how many threads I can cut continuously with this D6-class plug tap?

Chip packing in the straight flutes becomes the limiting factor during deep or repeated threading operations.

Does the bright uncoated finish affect heat buildup during all-day threading?

The uncoated high-speed steel runs warmer than coated alternatives, so cutting fluid is essential for heat control.
