Cleveland C01027 Jobber Drill Bit Wire 74 Hss

Product Description

The CLEVELAND C01027 is a jobber-length drill bit in wire gauge size 74, with a decimal diameter of 0.0225 inches. Made from high speed steel with an oxide finish coating, it features a standard 118-degree split point, a right-hand spiral flute, and a straight-cylindrical shank. The web-thinned, tapered web design reduces feed pressure and improves centering at the start of a cut. This bit is built to Series 2002 ASME B94.11M and DIN 338 standards. It is a general-purpose tool suited for machinists, maintenance technicians, and fabricators working in precision drilling applications.

The C01027 is designed for drilling into cast iron and steel. Its 0.25-inch flute length and 1-inch overall length make it appropriate for tight-access locations and small-diameter through-holes. The two-flute spiral configuration promotes chip evacuation in ferrous materials. This bit is typically used in bench drill presses, hand drills, and CNC setups where small wire-gauge hole sizes are required. It sells in single-piece packages with a minimum order quantity of 10 units.

Key Features

• Wire gauge size 74 with a 0.0225-inch decimal diameter for precision small-hole work
• High speed steel construction with oxide coating for corrosion resistance and heat management
• 118-degree standard point angle with web-thinned, tapered web for reduced entry force
• Right-hand, regular spiral flute for efficient chip removal in steel and cast iron
• Straight-cylindrical shank diameter of 0.0225 inches for standard chuck compatibility
• Meets ASME B94.11M and DIN 338 standards

Compatibility

Designed as a general-purpose jobber-length drill bit for use in cast iron and steel. Primary workpiece materials specified by the manufacturer are cast iron and steel.

Installation Notes

This drill bit is installed by machinists and maintenance technicians using standard drill chucks on bench presses, hand drills, or CNC machines. Secure the shank fully in the chuck before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. At this small diameter, excessive feed pressure or off-center starting can cause bit breakage — use a center punch or pilot point to locate the hole before drilling. Replace the bit if runout, chipping, or diameter tolerance drift is observed.
