Cleveland C71133 Jobber Drill Bit Wire 33 Hss Oxide

Product Description

The CLEVELAND C71133 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel with an oxide coating for added lubricity and surface protection, this bit carries a wire gauge size of 33, corresponding to a decimal diameter of 0.1130 inches. It features a standard 118-degree point angle, a two-flute spiral configuration with a regular helix, and a web-thinned, tapered web for reduced thrust and easier starting. Overall length is 2.625 inches with a 1.5-inch flute length and a straight-cylindrical shank. The C71133 meets ASME B94.11M and DIN 338 standards and is suited for use in hand drills, drill presses, and CNC applications.

This bit is intended for production and maintenance drilling where a small-diameter, wire-gauge drill is required. The 0.1130-inch diameter falls in the 0.1000 to 0.1500 inch size range, making it appropriate for tapping pilot holes, clearance holes, and precision work in light gauge materials. Electricians, plumbers, HVAC technicians, and general maintenance trades commonly use wire gauge drill bits for routing small-bore passages and preparing fastener holes. Sold individually per package with a minimum order quantity of 12 units.

Key Features

• High speed steel construction provides durability across ferrous and non-ferrous materials
• Oxide finish reduces friction and provides corrosion resistance during storage and use
• 118-degree standard point angle for general-purpose material entry
• Web-thinned, tapered web reduces required feed force and improves chip clearance
• Regular spiral flute with 4xD flute-to-diameter ratio promotes efficient chip evacuation
• Meets ASME B94.11M and DIN 338 dimensional standards for consistent sizing

Compatibility

Designed as a general-purpose jobber-length drill bit in wire gauge size 33, compatible with standard 3-jaw drill chucks accepting straight-cylindrical shanks at 0.1130 inches diameter.

Installation Notes

Install in a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid when drilling hardened or ferrous materials to extend tool life. Replace the bit if the cutting edges show visible wear, chipping, or if the drill begins to wander off-center.
