Drill bit for metal EPM HSS cylindrical 3.5 mm 2 pcs (E-500-1035)

Cylindrical HSS drill bits by EPM, diameter 3.5 mm, pack of 2. These high‑speed steel bits are designed for drilling metal and provide wear resistance and consistent cutting performance for general metalworking tasks. The straight cylindrical shank fits standard chucks in hand drills and drill presses, enabling accurate 3.5 mm holes in steel, cast iron and non‑ferrous metals when used with appropriate speeds and lubrication.

Advantages

The EPM HSS drill bits offer a hard, wear‑resistant cutting edge and good heat tolerance typical of high‑speed steel. Their cylindrical shank ensures stable clamping and compatibility with a wide range of drilling tools. Supplied as a pair, they provide immediate replacement or spare for repeated operations. The bits are suitable for general‑purpose metal drilling where dimensional accuracy and tool life are important.

Suitable for

• Drilling precise 3.5 mm holes in steel components
• Working with cast iron and non‑ferrous metals (aluminium, brass, copper)
• Use in hand drills and bench or pillar drill presses
• Maintenance, repair and light fabrication tasks

Key specifications

• Material: high‑speed steel (HSS)
• Shank type: cylindrical / straight shank
• Drill diameter: 3.5 mm
• Quantity: 2 pieces per pack
• Typical applications: metal drilling, general‑purpose machining

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring the shank is clamped firmly and the bit is aligned. Select an appropriate spindle speed for the metal being drilled (lower speeds for harder steels, higher speeds for softer non‑ferrous metals) and apply cutting fluid or lubricant to reduce heat and improve tool life. Start drilling with light, steady pressure; periodically withdraw the bit to clear chips and reapply lubricant if necessary. After use, clean chips from the flutes and store the bits dry to prevent corrosion.

Usage recommendations

For best results when drilling steel, use moderate cutting speeds and cutting fluid. Avoid excessive feed pressure to reduce risk of bit breakage. Replace the bit when wear or dullness leads to poor hole quality.
