Drill Bit for Metal GRAPHITE Hex Shank 5.0 mm, 2 pcs

GRAPHITE Drill Bit for Metal with a 5.0 mm diameter comes as a set of two pieces with a hex shank designed for secure fitting in hex chucks and quick-change holders. These bits are intended for drilling through various metal components where a precise 5.0 mm hole is required. The hex shank ensures stable seating during rotary use, reducing slippage and improving control when working with hand-held drivers or impact-compatible holders.

Advantages

The hex shank design provides reliable retention in hex chucks and quick-change systems, enabling faster bit changes and improved torque transfer. Supplied as a two-piece set, the bits offer a spare or alternative for repeated tasks. The 5.0 mm diameter is a common size for fastening and clearance holes in metalwork, and the bits are manufactured to deliver consistent hole diameter and alignment when used with appropriate speeds and clamping.

Suitable for

• Drilling precise 5.0 mm holes in steel and other metals
• Workshop and maintenance repair tasks
• Use with hex chucks, quick-change holders, and compatible hand drivers
• Preparation of holes for bolts, screws, and dowel fittings in metal parts

Key specifications

• Diameter: 5.0 mm
• Quantity: 2 pieces per set
• Shank type: Hex shank for secure seating
• Application: Drilling in metal

How to use

Secure the workpiece firmly in a vise or with clamps to prevent movement. Install the drill bit into a compatible hex chuck or quick-change holder, ensuring it seats fully. Select an appropriate drilling speed and feed rate for the metal being worked; lower speeds and steady pressure are generally recommended for harder steels. Apply cutting fluid where necessary to reduce heat and extend bit life. Withdraw the bit periodically to clear chips and prevent clogging.

Usage recommendations

Wear appropriate personal protective equipment, including safety glasses and gloves. For best results, pre-center the hole with a center punch when drilling thicker or harder metal, and use cutting fluid for heat dissipation. Inspect bits for wear and replace when cutting performance declines to maintain hole accuracy.
