Straight Insert Tool Holder w/55° insert

This holder features a centered design (not offset to either side) and includes a 55° carbide insert, a hold-down screw, and a Torx key for installation. It has a 3/8″ square shank that fits standard 3/8″ tool posts. The straight tip design allows for general-purpose turning operations in either direction. The cutting tip is positioned 0.375″ from the bottom of the holder, which conforms to industry standards. The holder is constructed from case-hardened steel and finished with black oxide for enhanced durability and corrosion resistance.

Though more costly than traditional tools, each insert offers two usable cutting edges. When one edge becomes dull or chipped, simply rotate the insert 180° to access a new cutting surface—essentially providing two tools in one.

About the Carbide Inserts

While high-speed steel (HSS) tools remain the primary choice for miniature machine work due to their affordability and ease of resharpening, inserted-tip carbide tools offer significant advantages in specific applications. Carbide inserts excel in cutting harder materials, improving efficiency and tool life—making them invaluable in many professional machining environments.

Safety Note

Carbide inserts can produce extremely hot chips and may shatter under stress. Always wear appropriate eye protection and safety gear when using these tools.

Certain materials, such as tool steel, may form long, continuous chips that can wrap around the workpiece like steel wool. To minimize this, use a chip brush frequently or pause machining to remove chip buildup. These “bird’s nests” can ignite from hot chips, so maintain a clean workspace near the cutter.
