Drill bit EPM HSS cylindrical for metal 4.5 mm model E-500-1045

Drill bit EPM HSS cylindrical for metal 4.5 mm model E-500-1045 is a solid high-speed steel twist drill designed for accurate holemaking in ferrous and non-ferrous metals. With a 4.5 mm cutting diameter and a standard cylindrical shank, this HSS drill bit is intended for use in hand-held drills and bench drill presses. The geometry and material of the cutting edges deliver consistent drilling performance for maintenance, fabrication and repair operations where a durable, general-purpose metal drill is required.

Advantages

The high-speed steel construction provides good hardness and heat resistance during intermittent metal drilling, reducing wear and extending cutting life compared with standard carbon steel bits. The cylindrical shank ensures secure clamping in standard drill chucks and allows quick exchange between tools. The 4.5 mm diameter offers a balance between precision and penetration speed for typical metalworking tasks.

Suitable for

• Drilling holes in steel, stainless steel and non-ferrous metals
• Maintenance and repair work in workshops and industrial settings
• Fabrication and light engineering tasks requiring precise small-diameter holes

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 4.5 mm
• Shank type: cylindrical (straight)
• Flute type: twist
• Intended use: metalworking (ferrous and non-ferrous metals)

How to use

Secure the drill bit in a properly tightened drill chuck to minimize runout. Mark and center-punch the drilling location to improve accuracy, then start drilling at low speed to establish the hole and increase speed as appropriate for the material and heat management. Use cutting lubricant when working with steel or stainless steel to reduce friction and extend tool life. Apply steady, moderate feed pressure; avoid excessive force that can cause bit breakage or accelerated wear.

Usage recommendations

For best results when drilling metals, use appropriate cutting fluid, maintain correct spindle speed for the 4.5 mm diameter and material, and replace the bit if wear or chipping appears at the cutting edges. Store the drill bit in a dry place to prevent corrosion and inspect the shank and flutes before use to ensure safe clamping and chip evacuation.
