EPM HSS straight shank metal twist drill bit 3.3 mm 2 pieces E-500-1033

The EPM HSS straight shank metal twist drill bit with a diameter of 3.3 mm is supplied as a set of two pieces and is engineered for precise drilling across various materials. Manufactured from high-speed steel, these drill bits deliver reliable performance and durability when working with steel, cast iron, and other ferrous and non-ferrous metals. They are well-suited for everyday workshop tasks as well as demanding industrial applications where accuracy and consistency are required.

Advantages

Constructed from quality high-speed steel, these drill bits offer enhanced wear resistance and maintain structural integrity during extended use. The straight shank design ensures compatibility with standard drill chucks, providing a secure grip and minimizing slippage during operation. The 3.3 mm diameter is precisely calibrated to support accurate hole creation for fasteners, threading, or general assembly work. The inclusion of two identical bits in the set ensures you have a ready backup on hand during continuous projects.

Suitable for

• Drilling precise 3.3 mm holes in structural steel and cast iron
• Working with various ferrous and non-ferrous metals in metalworking shops
• Maintenance, repair, and general industrial fabrication tasks
• Handheld drilling and stationary drill press operations

When it may not be suitable

These drill bits are not intended for drilling dense masonry, concrete, or reinforced stone structures, as high-speed steel is designed specifically for metal and wood applications. They may also be less effective when used on extremely hardened alloy steels without appropriate cooling and specialized drilling speeds.

Key specifications

• Material: High-speed steel (HSS)
• Bit diameter: 3.3 mm
• Shank type: Straight shank
• Quantity: 2 pieces per set
• Application: Metal drilling

How to use

Secure the drill bit firmly into the chuck of your power drill or drill press, ensuring it is centered properly. Mark your drilling point clearly on the metal surface and use a center punch to create a pilot dimple that prevents the bit from wandering. Apply steady, moderate pressure while maintaining an appropriate drilling speed suited for metal. For optimal results and extended bit lifespan, use a suitable cutting fluid or lubricant during the drilling process, especially when working with harder metals.

What to consider before purchase

• Verify that a 3.3 mm hole diameter matches your specific project requirements or fastener size
• Ensure your drilling equipment is compatible with straight shank drill bits
• Assess the material you intend to drill to confirm it falls within ferrous and non-ferrous metal categories

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses, when drilling metal. Clear metal chips regularly from the work area and avoid applying excessive lateral pressure to prevent bit breakage.
