Frequently Asked Questions
Q: What materials can the Extra Long HSS Twist Drill Bits cut through?
A: These HSS straight-shank twist drill bits are designed for use on wood, soft metals (such as aluminium and mild steel), plastics, and composite materials. The high-speed steel construction provides the hardness needed to maintain a sharp edge across multiple material types.
Q: What drill chuck is compatible with these straight shank drill bits?
A: The straight (cylindrical) shank is compatible with standard 3-jaw keyed and keyless drill chucks found on most corded and cordless power drills, as well as drill presses. Simply secure the shank firmly in the chuck before use.
Q: Why choose extra long 150mm drill bits over standard length bits?
A: Standard drill bits are typically 50–75mm long, which limits their reach in deep or confined spaces. At 150mm, these extra long bits allow you to drill through thick stock, reach into deep cavities, and work in tight spots — making them an essential addition to any serious toolkit.
Q: How do I maintain and extend the life of HSS drill bits?
A: To maximize the lifespan of your HSS drill bits, use cutting fluid or lubricating oil when drilling metal, run at appropriate speeds for the material, avoid excessive pressure, and store bits in a protective case or roll to prevent edge damage. Re-sharpening with a dedicated bit sharpener when tips dull will also extend service life significantly.
