Drill Bit EPM HSS cylindrical 4.8 mm, model E-500-1048

Drill Bit EPM HSS cylindrical 4.8 mm, model E-500-1048 is a straight-shank high-speed steel (HSS) cutting tool with a 4.8 mm cutting diameter, designed for precise drilling in metal and other suitable materials. The cylindrical shank fits standard chucks on hand drills and drill presses and the HSS material provides hardness and heat resistance for typical metalworking operations. This bit is intended for applications where accurate hole size and reliable cutting performance are required.

Advantages

The HSS construction offers wear resistance and thermal stability during intermittent to continuous drilling in ferrous and non-ferrous metals. The straight cylindrical shank ensures secure clamping in chucks and minimizes runout for improved accuracy. The 4.8 mm diameter provides a common, versatile hole size for many maintenance, fabrication, and installation tasks. The solid design delivers consistent hole quality and predictable tool life when used with appropriate speeds and lubrication.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum and other machinable metals
• Maintenance and repair tasks requiring precise 4.8 mm holes
• Use in hand-held electric drills and drill presses for metalworking
• Small fabrication and assembly operations in workshops and industrial settings

Key specifications

• Cutting diameter: 4.8 mm
• Material: High-speed steel (HSS)
• Shank type: Cylindrical (straight)
• Intended use: Metal drilling and similar materials
• Compatibility: Standard drill chucks on hand drills and drill presses

How to use

Secure the drill bit in a properly sized chuck ensuring minimal runout. Select a spindle speed appropriate for the workpiece material and bit diameter; lower speeds for harder metals, higher speeds for softer metals like aluminum. Use cutting fluid or lubricant when drilling ferrous metals to extend bit life and improve chip evacuation. Apply steady feed pressure without forcing the bit; withdraw periodically to clear chips when drilling deeper holes. After use, clean and store the bit in a dry place to prevent corrosion.

Usage recommendations

For best results, match spindle speed and feed to material hardness, use appropriate cutting fluid for metalwork, and inspect the bit regularly for wear or chipping. Replace the bit when performance degrades to maintain hole accuracy and prevent damage to workpieces or equipment.
