Accupro ACC-C312 Single Point Tool Bit Square Nose Carbide

Product Description

The ACCUPRO ACC-C312 is a neutral-hand, square nose single point tool bit designed for precision metalworking on manual and CNC lathes. The cutting tip is solid micrograin carbide, which provides fine grain structure for improved edge sharpness and resistance to chipping on interrupted cuts. The shank measures 5/16 inches wide by 5/16 inches high with an overall length of 6 inches. This geometry makes the ACC-C312 a compact, rigid option for shops running smaller toolpost setups. Machinists and toolroom technicians are the primary installers of this bit type.

The ACC-C312 is suited for a range of general metalworking operations on ferrous and non-ferrous workpieces. Documented cutting applications include chamfering, facing, forming, and turning. The neutral cutting direction works equally well in standard right-to-left turning passes and is often chosen when the operator needs directional flexibility without swapping tooling. The square nose profile is common in facing and forming passes where a flat cutting edge is required. This bit fits toolpost holders and boring bar setups accepting a 5/16 inch shank.

Key Features

• Solid micrograin carbide tip for improved edge retention and chipping resistance
• Neutral cutting direction for directional flexibility in turning operations
• Square nose profile suited for facing and forming passes
• 5/16 inch by 5/16 inch shank fits compact toolpost holders
• 6 inch overall length provides rigidity in standard lathe setups
• Industry Standard Number C-312 for cross-reference ordering

Compatibility

Designed as an OEM-style replacement and standard fitment for toolpost holders and lathe tool holders accepting a 5/16 inch square shank single point tool bit.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before changing or seating the bit, the machine spindle must be fully stopped and the lathe powered off. Seat the shank fully in the toolpost holder and secure per the holder manufacturer's clamping requirements. Inspect the carbide tip for micro-fractures before use, as carbide is brittle and should not be used if the tip shows visible damage.
