Cle-line C97311 7/32 Inch Hss Tin Jobber Drill Bit

Product Description

The CLE-LINE C97311 is a 7/32 inch (0.2188 inch decimal) high speed steel jobber drill bit with a titanium nitride (TiN) tip coating applied to the cutting end. It features a 118-degree split point for self-centering starts and reduced walking on metal surfaces. The regular spiral flute with a right-hand cutting direction clears chips efficiently during through-hole drilling. At 3.75 inches overall length with a 2.5-inch flute length, this bit fits standard drill chucks and drill presses used in metal fabrication, maintenance, and mechanical service work. It is installed and used by machinists, maintenance technicians, and metalworking tradespeople.

This jobber drill is suited for drilling steel, cast iron, and similar ferrous workpiece materials in both production and general-purpose maintenance settings. The 1500-TT series designation identifies its TiN tip coating and high-performance construction. With a straight cylindrical shank measuring 0.2200 inches in diameter and a 1.25-inch shank length, it seats securely in standard drill chucks without requiring adapters. Typical applications include through-hole drilling in sheet metal, structural steel, and cast iron components where a general-purpose HSS bit with enhanced tip durability is preferred over an uncoated option.

Key Features

• 7/32 inch (0.2188 inch) diameter with a tight tolerance of +0.0000 to -0.0007 inches
• 118-degree split point promotes self-centering and reduces drill walking
• TiN tip coating increases surface hardness at the cutting edge for extended tip life on ferrous materials
• Regular spiral flute with tapered web configuration for efficient chip evacuation
• Right-hand cutting direction, compatible with standard drill presses and handheld drills
• Conforms to ASME B94.11M standards with ANSI specification designation

Compatibility

Designed as a general-purpose replacement jobber drill bit for applications involving steel and cast iron workpieces. Compatible with any standard drill press or handheld drill accepting a straight cylindrical shank of 0.2200 inches in diameter.

Installation Notes

This drill bit is installed and used by machinists and maintenance technicians working with ferrous metals. Secure the straight shank firmly in the chuck before operation, and confirm the drill press or driver is set to a right-hand rotation. Wear appropriate eye protection and secure the workpiece before drilling. Replace the bit if the TiN tip coating is fully worn through or the cutting edges show chipping, as continued use on a degraded bit increases heat buildup and reduces hole quality.
