Drill Bit FANAR universal cylindrical 31 mm model W2-103811-0310

FANAR universal cylindrical drill bit with a 31 mm diameter (model W2-103811-0310) is a straight cylindrical cutting tool intended for drilling precise 31 mm holes. The tool is designed for general-purpose drilling in compatible materials and fixtures and is commonly used in workshops, construction sites, and maintenance tasks where a consistent bore diameter and straight-wall holes are required.

Advantages

The drill bit provides a consistent 31 mm hole with a straight cylindrical profile, ensuring dimensional stability and repeatability across multiple holes. Its universal design makes it compatible with a range of chucks and drilling machines that accept cylindrical shanks. The geometry of the cutting edges supports efficient chip evacuation and steady guidance during drilling, reducing the need for frequent re-centering or corrective finishing.

Suitable for

• Creating precise 31 mm diameter holes in wood and soft to medium-density materials
• Workshop drilling tasks on jigs and fixtures requiring straight cylindrical bores
• Construction and maintenance operations where a standardized 31 mm bore is specified
• Drilling operations that use bench drills, pillar drills, or compatible hand-held drills with appropriate chucks

Key specifications

• Cutting diameter: 31 mm
• Shank type: cylindrical (straight) shank for standard chucks
• Tool type: straight cylindrical drill bit suitable for through or blind holes depending on setup
• Typical applications: general-purpose drilling in workshop and construction environments

How to use

Select a drill press or hand-held drill with a chuck capable of securely holding a straight cylindrical shank of the drill bit. Mark the drilling position and, if necessary, use a center punch or pilot drill to improve accuracy. Secure the workpiece in a vise or fixture to prevent movement. Set the drill speed appropriate to the material being drilled and apply steady, even feed pressure to maintain hole straightness. Withdraw the bit periodically for chip clearing when drilling deeper holes, and finish the bore as required by the application.

Usage recommendations

Use cutting fluid or appropriate lubrication when drilling metals to reduce heat and wear. For wood and softer materials, adjust speed to avoid burning and use moderate feed. Ensure the drill chuck grips the cylindrical shank firmly and check alignment before starting. Inspect the cutting edges for wear and replace the bit if accuracy or cutting performance deteriorates.
