Drill bit FANAR cylindrical 7.3 mm W2-101811-0730

FANAR cylindrical drill bit W2-101811-0730 with a 7.3 mm cutting diameter is a straight-shank twist drill designed for precise drilling in a variety of workshop and metalworking applications. The cylindrical shank enables secure clamping in chucks and collets, while the 7.3 mm diameter matches tasks requiring this specific hole size. The drill geometry and manufacturing tolerances are intended to provide consistent hole quality when used with appropriate speeds, feeds, and cooling for the material being machined.

Advantages

This FANAR drill bit offers a uniform cylindrical shank for stable clamping and reduced runout. Its 7.3 mm cutting diameter is suitable for precise hole-making where that exact size is required. The tool is made to standard twist-drill form, providing reliable chip evacuation and straightforward sharpening when necessary. The combination of straightforward geometry and compatible shank form makes it adaptable to bench drills, drill presses, and portable drilling machines that accept straight shanks.

Suitable for

• Drilling through mild steel and common ferrous materials when using correct speeds and lubrication
• Workshop drilling tasks on drill presses and bench machines
• General maintenance and fabrication work requiring 7.3 mm holes
• Use in jigs and fixtures where a straight cylindrical shank is required

Key specifications

• Cutting diameter: 7.3 mm
• Shank type: cylindrical (straight) shank
• Tool form: twist drill
• Typical applications: metalworking, workshop and general drilling

How to use

Secure the drill bit in a compatible chuck or collet ensuring minimal runout. Select cutting speed and feed appropriate to the workpiece material—lower speeds for hard steels, higher speeds for softer materials—and apply suitable cutting fluid when drilling metals to extend tool life and improve surface finish. Start with a center punch or pilot mark to prevent walking, especially when drilling on flat surfaces, and use steady, even feed pressure through the cut. Retract occasionally when drilling deep holes to clear chips and maintain cooling at the cutting edge.

Usage recommendations

For best results when drilling metals, use recommended cutting oils and moderate speeds, monitor drill wear, and regrind to maintain correct point geometry when necessary. Verify compatibility with the machine spindle and clamping system before use to ensure safe and accurate operation.
