These drill bits are precision engineered to meet the needs of a variety of drilling applications, ensuring optimal performance in a variety of materials. At the heart of our product offering are specialized high-speed steel (HSS) drill bits. Whether you’re working with metal, wood, or other materials, high-speed steel construction ensures longevity, making these drills a reliable choice for professionals and DIYers alike.
An economic HSS drill used for drilling all non-alloy materials. The 135° split point prevents the bit from drifting and enables faster penetration.
• High Speed Steel (HSS)
• Black oxide finish
• Roll forged
• Manufactured to DIN 338
• Dimensionally precise
• High performance 135° split point tip eradicates the need to pre-drill/centre punch
An HSS (High-Speed Steel) drill bit is the most versatile and common type of twist drill bit, designed to cut through steel, aluminum, wood, and plastic. Built with a cylindrical shank to fit standard power drills, they are ideal for everyday site work and general-purpose drilling tasks.Common Types of HSS Drill BitsHSS-R (Rolled Forged): Black or gray, budget-friendly bits rolled under heat. Best for soft, non-demanding materials.HSS-G (Ground): Highly precise and sharp, completely machined from solid steel. They last longer and drill cleaner holes.HSS-TiN (Titanium Nitride Coated): These golden bits have reduced friction, allowing them to withstand higher speeds and cut faster without overheating.HSS-Co (Cobalt): Usually containing 5% cobalt, these bronze-colored bits are designed for heavy-duty, high-heat applications like drilling through stainless steel or cast iron. 60 DEG M35 RED-X DOUBLE END NC SPOT DRILL
