Accupro ACC-C250 Single Point Tool Bit 1/4 in Square Nose

Product Description

The ACCUPRO ACC-C250 is a neutral-cutting, square nose single point tool bit designed for precision lathe and turning center operations. Built with a micrograin solid carbide tip brazed to a rigid shank, this tool bit delivers consistent edge retention and surface finish quality in demanding cutting conditions. The shank measures 1/4 inch wide by 1/4 inch tall, and the overall length is 6 inches, making it well suited for standard quick-change and lantern-style tool post setups. Machinists and tool-and-die professionals specify micrograin carbide grades for fine-grain structures that support sharper edges and improved wear resistance compared to standard carbide grades.

The ACC-C250 is used in general-purpose metal cutting applications including chamfering, facing, forming, and turning operations on manual lathes and CNC turning centers. Its neutral cutting geometry means the tool can be used in either direction without a dedicated left- or right-hand designation, offering layout flexibility in production and job-shop environments. The compact 1/4 inch shank size is typical for light-duty turning, second-operation work, and precision finishing cuts on ferrous and non-ferrous materials.

Key Features

• Micrograin solid carbide tip for sharper cutting edges and extended tool life compared to standard carbide
• Neutral cutting direction accommodates both left-hand and right-hand tool post orientations
• Square nose profile suited for facing, forming, chamfering, and turning applications
• 1/4 inch by 1/4 inch shank fits standard small-bore tool holders and quick-change tool posts
• 6 inch overall length provides adequate rigidity and reach for typical lathe tooling setups
• Industry standard designation C-250 for cross-reference with equivalent tooling specifications

Compatibility

Designed as an OEM-style replacement and direct-fit tool bit for standard 1/4 inch shank tool holders used in light-duty lathe and turning center applications. Industry standard number C-250 supports cross-referencing with equivalent tooling from other manufacturers.

Installation Notes

Installation is performed by machinists and toolroom technicians. Power down and lock out the lathe or turning center before setting or replacing tool bits. Seat the shank fully in the tool holder and tighten set screws to manufacturer specifications for the holder being used. Inspect the carbide tip for chips or cracks before each use and replace if tip integrity is compromised.
