Cleveland C70336 Screw Machine Drill Bit Wire 32 Hss

Product Description

The CLEVELAND C70336 is a screw machine length drill bit designed for high-speed steel cutting in metal fabrication and machining applications. Built to wire size 32 (0.1160 inches), it features a 135-degree split point that reduces walking on entry and requires no center punch on most materials. The parallel web construction and web-thinned geometry reduce thrust forces during drilling. Right-hand cut with a straight-cylindrical shank, this bit is built to heavy-duty grade tolerances and meets ASME B94.11M and NAS 907 Type C standards. Machinists, tool and die technicians, and industrial maintenance trades install this type of bit in standard drill chucks and CNC drill stations.

The C70336 is suited for drilling alloy steels and aluminum in production and maintenance environments where screw machine length bits are preferred for their rigidity and reduced deflection in short-reach applications. The 1.875-inch overall length and 0.875-inch flute length make it appropriate for shallow-hole work in tight setups. The bright uncoated finish makes it compatible with standard cutting fluids. It is sold individually with a minimum order quantity of 12 units.

Key Features

• Wire size 32 diameter — 0.1160 inches with a tolerance of +0.0000 to -0.0005 inches
• 135-degree split point reduces entry walking and lowers required thrust force
• Heavy-duty grade high-speed steel construction for alloy and aluminum workpieces
• Web-thinned, parallel web configuration for improved chip evacuation
• Screw machine length provides added rigidity over jobber-length bits in short-reach setups
• Meets ASME B94.11M and NAS 907 Type C specifications

Compatibility

Designed as a screw machine length replacement or production drill bit for use in standard straight-shank drill chucks, screw machine spindles, and CNC drilling setups targeting alloy steel and aluminum workpieces.

Installation Notes

Installation is performed by machinists and maintenance trades using standard drill press, hand drill, or CNC equipment with a compatible straight-shank chuck. Ensure the chuck is fully tightened and the workpiece is secured before drilling. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain hole tolerance. Inspect the cutting edges before each use — replace the bit if the point shows chipping or wear beyond acceptable limits.
