Cleveland C44659 HSS M2 Tool Bit
The Cleveland C44659 is a rectangular high-speed steel tool bit designed for lathe work. It serves machinists and metalworkers who need a durable blank for custom grinding cutting tools. The M2 grade steel provides reliable wear resistance for general-purpose machining tasks. This new accessory arrives ready for shaping to specific profiles.
Replaces Worn or Generic Blanks
This bit upgrades from dull, damaged or lower-grade tool blanks that require frequent regrinding. The jump is worth it when consistent edge retention reduces downtime on manual or CNC lathes. It suits operators who grind their own geometries rather than relying on disposable inserts. The right and left-hand suitability adds versatility for various turning operations.
Fits Standard Tool Holders
The rectangular blank fits common tool posts and holders sized for 3/4 by 1 inch cross-sections. Its 6-inch length allows multiple regrinds before replacement is needed. The non-beveled design gives the user full control over rake and clearance angles during grinding. No special clamping or coolant systems are required beyond standard lathe provisions.

Questions about this item
Will the 3/4 in by 1 in cross-section fit my tool post?
The blank measures 3/4 in wide and 1 in high, so it matches any tool post that accepts a 3/4 x 1 in rectangular shank.
How do I mount the bit and what step is often missed?
Clamp the 6 in blank in the tool post, then grind the cutting profile before use; the common error is skipping the grind and trying to cut with the square edge.
How long before the M2 high-speed steel needs regrinding?
M2 steel holds an edge well in general turning; regrind when the cutting face shows visible wear or the finish deteriorates.
