Cleveland C01836 Jobber Drill Bit Size 61 Hss Oxide

Product Description

The CLEVELAND C01836 is a jobber-length twist drill bit in wire gauge size 61, with a decimal diameter of 0.0390 inches. Built from high speed steel (HSS) with an oxide coating, it is designed for general-purpose drilling in production and maintenance environments. The 118-degree standard point angle and two-flute spiral design provide efficient chip evacuation and clean entry. Overall length is 38.10 millimeters (approximately 1.5 inches), with a straight-cylindrical shank of equal diameter. Licensed tradespeople, machinists, and maintenance technicians use this bit when working in tight-tolerance applications that call for small-diameter wire gauge tooling.

This bit is suited for drilling aluminum as its primary workpiece material, though the general-purpose grade also handles softer metals and plastics in light-duty applications. The regular spiral and tapered web with web thinning help reduce thrust force and improve hole quality in thin-stock and sheet material. It fits standard drill chucks and driver collets that accept a 0.0390-inch straight-cylindrical shank, making it compatible with benchtop drill presses, hand drills, and CNC spindles used in HVAC, electrical, and general fabrication work. Conforms to ASME B94.11M and DIN 338 standards.

Key Features

• Wire gauge size 61, 0.0390-inch diameter for precision small-hole work
• 118-degree standard point angle for general-purpose drilling
• High speed steel construction with oxide finish for reduced friction and light corrosion resistance
• Web-thinned, tapered web design lowers thrust and improves chip clearance
• Regular spiral, two-flute geometry optimized for aluminum and soft metals
• Meets ASME B94.11M and DIN 338 dimensional and performance standards

Compatibility

Designed as an OEM-style general-purpose jobber drill bit for use in any standard chuck or collet accepting a 0.0390-inch straight-cylindrical shank; primary recommended workpiece material is aluminum per manufacturer specification.

Installation Notes

Install into a properly sized drill chuck or collet and tighten securely before operation. Secure the workpiece to prevent movement during drilling. Use appropriate cutting fluid or lubricant when drilling metals to extend bit life and improve hole finish. Inspect the cutting edges before each use and replace worn or chipped bits to maintain hole-diameter tolerance within the specified range of -0.0005 to 0.0000 inches.
