Micro 100 LC-312100 Carbide Tool Bit

This Micro 100 LC-312100 is a single-point brazed tool bit made from carbide with a zinc shank. It measures 6 inches long and 5/16 inches wide. The left-hand geometry suits specific turning operations on a lathe. It is a new hand tool intended for metalworking setups.

Machinists needing left-hand carbide tooling

The left-hand orientation and carbide construction suit machinists cutting on the left side of a workpiece. Builders who need right-hand tooling or high-speed steel bits should look at something else. Shops requiring indexable inserts or different shank dimensions will not find them here.

5/16 inch shank width decides fit

The 5/16 inch shank width is the single specification that determines whether this bit fits your tool holder. Verify your holder accepts this exact width before ordering. The 6 inch overall length and left-hand carbide tip follow from that shank size.

Questions about this item

What does the 5/16 in width mean when the bit is mounted in a tool holder?

The 5/16 in shank width sets the holder size needed; the bit fits holders machined for that dimension.

How does the left-hand orientation change the way the tool engages the workpiece?

Left-hand geometry directs chips away from the operator and suits lathes turning counter-clockwise.

What physical space does the 6 in length require inside the machine envelope?

The 6 in overall length needs at least that much clear travel in the tool post to avoid interference.
