Value Collection 01370105 Screw Machine Drill Bit 5/32

Product Description

The VALUE COLLECTION 01370105 is a screw machine length cobalt drill bit designed for heavy-duty drilling applications where stub-length rigidity and heat resistance matter. At 5/32 inch (0.1562 inch decimal) in diameter, the bit features a 135-degree split point that starts on contact without walking, reducing the need for a center punch. The overall length is 2-1/16 inches with a 1-inch flute length, keeping the tool compact for use in tight spaces or drill presses. Constructed from cobalt steel, it handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel bits. Right-hand cutting direction with a regular spiral flute pattern. Sold individually.

Screw machine length drill bits are a standard tool in metal fabrication shops, machine shops, and maintenance environments. The shorter body length compared to jobber-length bits provides greater rigidity and reduces deflection when drilling through ferrous metals, stainless steel, cast iron, and other hard materials. This bit suits drill press operations, CNC setups, and hand-held drilling where stub-length control is preferred. Machinists, maintenance technicians, and tool-and-die tradespeople commonly reach for cobalt screw machine bits when jobber-length bits flex or wear prematurely on tough stock.

Key Features

• Cobalt construction for heavy-duty cutting in hard and abrasive metals
• 135-degree split point starts on contact and reduces bit walking
• Screw machine (stub) length body at 2-1/16 inches OAL for maximum rigidity
• 1-inch flute length with regular spiral pattern for efficient chip evacuation
• Straight shank fits standard drill chucks without adapters
• Right-hand cutting direction; 2-flute geometry

Compatibility

Designed as a standard screw machine length drill bit for use in any drill press, hand drill, or CNC spindle equipped with a chuck accepting a straight-shank bit in the 5/32-inch size range.

Installation Notes

Secure the straight shank firmly in the drill chuck before use and verify the workpiece is clamped or fixtured to prevent rotation. Use appropriate cutting fluid or coolant for hard metals to extend bit life, even though this bit does not support through-tool coolant. Inspect the split point for chipping before each use; a damaged point will cause runout and oversized holes. Cobalt bits can be resharpened, but only on grinding equipment rated for cobalt-grade tooling.
