Cleveland 54847 Straight Flute Tap

The Cleveland 54847 is a straight-flute hand tap designed for cutting internal threads in a variety of materials. It suits machinists and maintenance technicians who need reliable thread creation for repair or fabrication work. The plug chamfer offers a balanced start for both through-hole and blind-hole applications. This tool is not for buyers who require automated machine tapping or coated cutting geometry.

3/4"-16 UNF Thread Capacity

The tap cuts a 3/4"-16 UNF thread with a 2-inch thread length and an overall length of 4.25 inches. It conforms to a 2B class of fit with an H3 thread limit for standard precision requirements. The 75 percent thread drill size is 17.50 mm, providing the correct core diameter for proper engagement. It runs out when materials demand spiral-point or spiral-flute evacuation for deep blind holes.

High-Speed Steel Bright Finish

Constructed from high-speed steel with a bright uncoated finish, the tap delivers standard wear resistance for general-purpose ferrous and non-ferrous metals. The right-hand cutting direction matches conventional threading operations. The straight-flute design requires manual chip clearing during use, which slows production in high-volume settings. The lack of coating limits tool life in abrasive or high-temperature alloys.

Questions about this item

Will the 3/4"-16 plug tap cut cleanly in a pre-drilled hole made for an older H3-limit tap?

Yes, the tap uses H3 thread limit and Class 2B fit, matching the same allowance as other H3 taps for consistent engagement.

How do I confirm the 3/4"-16 tap is cutting to the correct depth and thread form after setup?

Check that threads reach the full 2 in thread length, measure pitch diameter within 2B tolerance, and verify the 75 % thread drill size of 17.50 mm was used.

Does the Cleveland 54847 package include a 17.50 mm drill bit or only the 4.25 in high-speed steel tap?

Only the straight-flute tap is supplied; the 17.50 mm drill bit for 75 % thread depth must be purchased separately.
