Lathe Tool Blank for Machinists
This Cleveland HSS M2 rectangular tool bit serves machinists and tool-room personnel who grind custom lathe tools. High-speed steel grade M2 provides the wear resistance required for general-purpose turning on ferrous and non-ferrous materials.
Ready to Grind, No Mounting Required
The blank arrives unground and non-beveled, so the user shapes the cutting geometry to suit the job. Common issues include overheating during grinding, which can reduce hardness, and selecting an incorrect relief angle that leads to chatter or poor chip control.
Verify Shank Dimensions Before Ordering
Confirm that your tool holder or tool post accepts a 5/8 in by 7/8 in cross-section and that the 6 in overall length fits within the machine's envelope. The blank is supplied right- and left-hand neutral, so no hand-specific orientation is imposed.

Questions about this item
How can I confirm the Cleveland HSS M2 tool bit is ready for use after grinding?
The bit is made from high-speed steel grade M2 and supplied as a non-bevelled rectangular blank; after you grind the cutting geometry, a sharp, consistent edge along the 5/8 in by 7/8 in face shows it is prepared correctly.
What comes in the package and what must I supply myself?
The package contains the Cleveland C44656 rectangular tool bit 851 only; you will need to provide a lathe tool holder, grinding equipment for shaping the cutting edges, and any coolant or lubricant you prefer.
Which version of this tool bit should I select for my lathe?
This listing is for the single 851 specification — 5/8 in wide, 7/8 in high, 6 in long, right-and-left-hand non-bevelled HSS M2 — so choose it when those exact dimensions match your tool holder.
