Cleveland C44547 Square Tool Bit

The Cleveland C44547 is a square tool bit made from M42 cobalt material. It measures 3/8 inch in overall width and height with a 3 inch overall length. This lathe tool blank suits machinists and metalworkers needing a durable cutting blank for turning operations. The non-beveled design works for both right-hand and left-hand applications.

Installation and common issues

The bit fits standard tool holders that accept 3/8 inch square shanks. Secure it firmly to prevent movement during cutting passes. A loose fit can cause chatter or tool breakage under load. Ensure the holder is clean and the bit seats fully before tightening. Improper alignment leads to poor surface finish and dimensional errors.

Suitable users and alternatives

This tool bit suits machinists working with cobalt-compatible materials on manual or CNC lathes. Buyers needing beveled cutting edges or different shank dimensions should look at other tool bit styles. Those requiring indexable inserts or carbide grades will need a different product type. The fixed 3/8 inch square size limits holder compatibility.

Questions about this item

How do I verify the 3/8 in square blank is cutting cleanly after I grind it?

Grind the bit to your required profile, then take a light test cut in the workpiece material; a smooth finish and consistent chip formation show the M42 cobalt edge is performing correctly.

What comes with the C44547 tool bit and what must I supply?

The package contains the single 3 in long, 3/8 in square cobalt blank; you will need to provide your own tool holder, grinding equipment and workpiece.

Which version of the C44547 should I choose for general lathe work?

The C44547 is offered in one 3/8 in square, 3 in length M42 cobalt configuration, so select this version when you need a right- or left-hand non-bevelled blank for custom grinding.
