Value Collection 01378330 Size 33 Cobalt Drill Bit

Product Description

The VALUE COLLECTION 01378330 is a screw machine length (stub length) cobalt drill bit designed for drilling in hard and abrasive materials where standard high-speed steel bits wear prematurely. Built to a wire gauge Size 33 (0.1130 inch decimal equivalent), this bit features a 135-degree split point for self-centering starts without a center punch. The shorter overall length of 1-7/8 inches provides added rigidity and reduced deflection, which is critical when drilling tough alloys, stainless steel, and hardened workpieces. The right-hand, two-flute regular spiral geometry clears chips efficiently and keeps the cutting edge engaged. This is a heavy-duty grade bit suited for production and maintenance drilling applications.

This bit is used in metalworking, maintenance, and fabrication settings where short, rigid tooling is preferred over jobber-length bits. The screw machine length format makes it well suited for drill presses, CNC machining centers, and hand drills in confined workspaces. Typical applications include drilling pilot holes, clearance holes, and through holes in ferrous and non-ferrous metals. The cobalt construction handles the elevated heat generated in interrupted cuts and high-speed production runs. Electricians, pipefitters, HVAC technicians, and sheet metal fabricators commonly keep screw machine length cobalt bits on hand for hard-material work.

Key Features

• Cobalt tool material for extended wear life in hard and abrasive materials
• 135-degree split point self-centers on contact, reducing walk and eliminating the need for a center punch
• Screw machine (stub) length at 1-7/8 inches overall provides maximum rigidity and minimizes deflection
• Right-hand cutting with two-flute regular spiral for efficient chip evacuation
• Straight shank compatible with standard drill chucks and collets
• Heavy-duty grade construction rated for production and repetitive drilling cycles

Compatibility

Designed as an OEM-style replacement or stock tooling option for any standard drill chuck or collet accepting a straight-shank bit in the Size 33 wire gauge range (0.1130 inch diameter).

Installation Notes

Secure the straight shank firmly in the drill chuck before operation and verify chuck runout is within acceptable tolerance to avoid premature bit wear. Use cutting fluid or cooling lubricant when drilling ferrous metals to extend bit life and prevent heat buildup. Reduce feed pressure as the bit breaks through to avoid grabbing and bit breakage. This bit falls in the 0.1000 to 0.1500 inch diameter range, so match spindle speed to material hardness and diameter using a standard speeds-and-feeds reference chart.
