Cleveland C54093 Straight Flute Tap

The Cleveland C54093 is a straight flute tap designed for creating UNF threads in a #2-64 size. It is made from high speed steel with a bright uncoated finish and features a right hand thread direction. This new accessory suits machinists and maintenance technicians who need to cut internal threads in through holes or blind holes with adequate clearance.

Taper chamfer and three flute design

The taper chamfer provides a gradual start that helps alignment when entering the workpiece. Three flutes offer space for chip evacuation while maintaining cutting strength. A thread length of .44 in and overall length of 1.75 in define the cutting reach. The 75 percent thread drill size of 1.80 mm and H2 thread limit with 2B class of fit guide the preparatory drilling and tolerance requirements.

Suitable for general purpose threading tasks

This tap suits users cutting #2-64 UNF threads in materials compatible with high speed steel. It is not for buyers who need a bottoming or plug chamfer for threading close to the bottom of a blind hole. It is not for applications requiring a coated tool for extended wear resistance in abrasive or high temperature alloys. It is not for left hand thread requirements.

Questions about this item

What thread depth can the 1.75 in overall length tap reach in a single pass?

The straight flute tap has a thread length of .44 in, so it cuts threads up to that depth per pass.

How much heat builds up when tapping #2-64 UNF holes all day with this uncoated high-speed steel tool?

Bright finish HSS generates more friction heat than coated taps; use cutting fluid and pause between holes to manage temperature.

Which drill bit must I already own to prepare the 75 percent thread hole for this H2 limit tap?

A 1.80 mm drill bit produces the correct 75 percent thread drill size for the #2-64 UNF 2B class of fit.
