Drill Bit EXO EXO PRO Steel Vacuum 2.3 mm GRB

EXO PRO Steel Vacuum 2.3 mm GRB is a precision metal drill bit designed for narrow-diameter drilling tasks. Manufactured by EXO, this 2.3 mm cutting-size bit is intended for use in handheld drills and drill presses where accurate, slim holes in metal and similar materials are required. The steel construction offers suitable rigidity for routine metalworking and general material penetration tasks while the vacuum-style flute minimizes chip build-up during drilling.

Advantages

This drill bit provides consistent 2.3 mm hole size with good dimensional stability for repetitive operations. The steel material and vacuum-style flute enhance chip evacuation and reduce clogging compared with standard straight-flute bits. Its slim profile allows access to tight spaces and supports precise alignment when used with standard drill chucks and fixtures.

Suitable for

• Precision drilling in thin metal sheets and light alloys
• Handheld drilling and drill press operations requiring small diameters
• Electrical and electronic enclosures where compact holes are needed
• General-purpose prototypes and light fabrication work

Key specifications

• Cutting diameter: 2.3 mm
• Material: steel
• Flute type: vacuum-style flute for improved chip removal
• Intended use: metal and general material penetration
• Compatibility: handheld drills and drill presses with appropriate chuck

How to use

Select a drill speed and feed appropriate for the metal or material being machined; lower speeds are generally recommended for harder metals. Secure the workpiece firmly in a vise or fixture to prevent movement. Fit the 2.3 mm EXO PRO bit into the drill chuck ensuring it is centered and tightened. For best results, start with a pilot or center punch mark to prevent walking, apply steady pressure, and periodically withdraw the bit to clear chips. Use cutting fluid where appropriate to reduce heat and extend tool life.

Usage recommendations

Use the EXO PRO Steel Vacuum 2.3 mm GRB at controlled speeds for metalworking, keep the drill bit cooled with appropriate lubricant during prolonged drilling, and inspect the cutting edge regularly; replace the bit when wear affects hole accuracy or increases force requirements.
