Cleveland C96117 Spiral Point Tap 5/16-24 UNF Cobalt 3 Flutes

SKU CH-DF7H-5Q4TK

Cobalt spiral-point tap cuts 5/16-24 UNF threads in through holes with three flutes for efficient chip evacuation

  • Cuts clean threads in tough materials with cobalt construction
  • Starts easily in through-holes using spiral-point design
  • Removes chips efficiently through three-flute geometry
  • Resists wear and corrosion with black-oxide finish
  • Matches 5/16-24 UNF specs for precise fit

Cleveland C96117 Spiral Point Tap

The Cleveland C96117 is a cobalt spiral point tap designed for threading operations in metalworking applications. It creates unified national fine threads with a right-hand orientation for standard fastening requirements. This cutting tool suits machinists and maintenance technicians who need reliable thread production in through-hole applications.

5/16-24 UNF thread specification

The tap cuts a 5/16 inch diameter thread with 24 threads per inch in the unified national fine series. Cobalt construction with black oxide finish provides wear resistance during repeated use. Three flutes and a spiral point design push chips ahead of the cutting action for cleaner threads in through holes. The 2B class of fit ensures standard tolerance for general-purpose assembly.

Through-hole threading with standard tooling

The spiral point geometry requires a through-hole or deep blind hole with chip clearance beyond the thread depth. A 75 percent thread drill size I prepares the correct hole diameter before tapping. Right-hand cutting direction works with conventional tap handles, wrenches or powered tapping heads. The 3 35/64 inch overall length and 1 3/8 inch thread length reach standard workpiece thicknesses without special tooling.

Questions about this item

What does the 5/16-24 UNF thread size mean for the holes I can tap?

It cuts a 5/16 inch diameter unified fine thread with 24 threads per inch, matching a Class 2B fit for standard nuts and bolts.

How does the spiral point design affect chip flow in a through hole?

The spiral point pushes chips ahead of the tap, preventing clogging and allowing continuous cutting in through holes without frequent reversal.

What drill size and shank fit are required to use this tap?

Use a number I drill for a 75 percent thread depth; the tap has a standard square shank that fits common tap wrenches or holders.
