Frequently Asked Questions
Q: What materials can the HSS M35 cobalt twist drill bits cut through?
A: These HSS M35 cobalt twist drill bits are designed to cut through a wide range of materials including wood, soft and mild steel, aluminium, copper, plastic, and other non-ferrous metals. The 5% cobalt content makes them particularly effective on harder metals that would quickly dull standard HSS bits.
Q: What sizes are included in this 15-piece drill bit set?
A: The set includes 15 drill bits ranging from 1.5mm up to 6.5mm in incremental sizes, giving you a comprehensive selection for precision pilot holes and larger bore work across a variety of projects.
Q: Are these cobalt drill bits compatible with standard cordless drills?
A: Yes. The standard round shanks on these HSS M35 cobalt twist drill bits are compatible with most cordless drills, bench drill presses, and rotary tools available on the market today.
Q: What is the advantage of the 135° split point tip?
A: The 135° split point tip is self-centring, meaning the bit starts cutting immediately upon contact without sliding across the surface. This reduces the need for a centre punch and results in more accurate, cleaner holes on both wood and metal.
