Drill bit for metal GRAPHITE 9.0 mm hex shank model 54T717

Drill bit for metal GRAPHITE 9.0 mm hex shank model 54T717 is a straight-shank twist drill designed for drilling steel and various ferrous and non-ferrous metals. The 9.0 mm cutting diameter and reinforced flutes provide stable chip evacuation while the hexagonal shank ensures secure clamping in chucks and quick-change holders, reducing slippage during heavy-duty or repetitive drilling operations. Designed for use in workshop and construction environments, this drill bit performs best when paired with correct cutting speeds and appropriate lubrication.

Advantages

The hexagonal shank delivers reliable grip and prevents rotation in quick-change chucks. Precision-ground point geometry improves centering and reduces walking at drill start. Solid construction and optimized flute design support efficient chip removal and extend tool life when used with proper cutting parameters. The 9.0 mm diameter offers a common size for fastening and through-hole applications in metalworking.

Suitable for

• Drilling mild and low-alloy steels
• Drilling non-ferrous metals such as aluminum and brass
• Workshop and maintenance tasks
• Construction site metalwork and installation
• Use with hand-held drills and drill presses featuring hex chucks or quick-change adapters

Key specifications

• Material application: ferrous and non-ferrous metals
• Cutting diameter: 9.0 mm
• Shank type: hexagonal shank for secure clamping
• Shank style: straight shank (hex profile)
• Point geometry: precision-ground tip for improved centering
• Flute design: optimized for chip evacuation

How to use

Mount the drill bit securely in a compatible hex chuck or quick-change holder. Select appropriate spindle speed based on the metal being drilled—lower speeds for harder steels and higher speeds for softer non-ferrous metals—while consulting tooling speed charts if available. Apply cutting fluid or lubricant to reduce heat and wear, and use steady feed pressure to maintain hole quality and extend tool life. Retract periodically on deep holes to clear chips and avoid clogging.

Usage recommendations

For best results, use cutting oil when drilling steel and moderate speeds with steady feed. Start holes with a smaller pilot drill when high positional accuracy is required. Inspect the bit for wear before use and replace when cutting performance deteriorates to avoid workpiece damage.
