Drill bit set GRAPHITE 4.8 mm hex shank for metal, 2 pcs

GRAPHITE drill bit set for metal includes two 4.8 mm diameter twist drill bits with a hexagonal shank designed for secure seating in hex chucks and quick-change holders. These bits are intended for drilling through a variety of metal materials where a precise 4.8 mm hole is required. The compact two-piece set is suited for workshop, construction and maintenance tasks using electric drills, impact drivers and cordless screwdrivers that accept hex shanks.

Advantages

The 4.8 mm drill bits feature a hex shank that reduces slippage in the chuck and enables faster bit changes. Hardened cutting edges and a geometry optimized for metal provide consistent chip removal and improved drilling accuracy. Supplied as a matched two-piece set, the bits offer simple replacement and backup on the job, reducing interruptions during repetitive drilling tasks.

Suitable for

• Drilling holes in steel and non-ferrous metals
• Workshop repairs and metal fabrication
• Maintenance and installation of metal components
• Use with hex-chuck holders, quick-change adapters and impact/drill drivers

Key specifications

• Diameter: 4.8 mm
• Quantity: 2 pieces
• Shank type: Hexagonal shank for secure grip
• Intended material: Metal (steel and non-ferrous metals)
• Drill type: Twist drill geometry optimized for metal drilling

How to use

Select an appropriate drill or driver that accepts hex shanks and secure the bit in the chuck or quick-change adapter. Mark and center-punch the drilling location on the metal surface to prevent wandering. Use moderate speed and steady feed pressure; for thicker or harder metals, use cutting fluid or lubricant and pause occasionally to clear chips and avoid overheating. Replace bits from the two-piece set when cutting performance decreases to maintain hole quality.

Usage recommendations

For best results when drilling metal, use a center punch before drilling, apply cutting lubricant for tougher alloys, and avoid excessive pressure or high speeds that can blunt the cutting edge. Store the bits dry and protected to prevent corrosion and ensure consistent fit in hex chucks.
