Why Choose M35 Cobalt Drill Bits?

Standard HSS bits can lose their edge quickly when working through hard metals and stainless steel. The cobalt content in M35 bits raises the material's hardness and heat tolerance significantly — so your bits stay sharper longer, even under sustained friction and pressure. This makes them a smart investment for anyone regularly working with demanding materials.

Frequently Asked Questions

Q: What materials can the M35 Cobalt Drill Bit Set cut through?

A: The M35 Cobalt HSS Drill Bit Set is designed to drill through a wide range of materials including stainless steel, hard metals, mild steel, wood, and plastics. The 5% cobalt alloy construction gives these bits the hardness and heat resistance needed to handle tough materials that would quickly wear out standard HSS bits.

Q: What sizes are included in the M35 Cobalt Drill Bit Set?

A: This set includes 7 precision-ground bits in the following sizes: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm — providing a comprehensive range for fine detail work through to medium-duty drilling tasks.

Q: Can I use these cobalt drill bits in a drill press as well as a handheld drill?

A: Yes! The M35 Cobalt Drill Bit Set is compatible with both handheld power drills and stationary drill presses, giving you flexibility across different workshop setups and project types.

Q: What makes M35 Cobalt bits better than standard HSS drill bits?

A: M35 Cobalt bits are alloyed with 5% cobalt, which significantly increases their hardness and heat resistance compared to standard high-speed steel (HSS) bits. This means they maintain their cutting edge longer, particularly when drilling through tough or abrasive materials like stainless steel and hard metals.
