Coffee 9.0mm HSS Twist Drill Bit HRC65-67 ,M35 Hss Drill Bits For Steel
High-speed steel (HSS) drill bits can drill wood, fiberglass, polyvinyl chloride (PVC) and soft metals such as aluminum.
Cobalt drill bits are extremely hard and dissipate heat quickly. They're mostly used for boring in aluminum and tough metals
such as stainless steel
Twist drills are usually available in sizes 3-10 mm plus. They are designed for drilling relatively small holes,
they sometimes tend to clog quickly especially when the wood is 'green' so when drilling deep holes (especially in
hardwood) the bits should be withdrawn regularly to remove the waste.

HOW TO DRILL IN METAL
Standard metal drill bits are fine for drilling in soft metals like copper and aluminium. But for hard metals such as stainless steel,
it’s best to use drill bits made of chrome vanadium, cobalt or titanium carbide. The HSS label indicates that the drill bit is made
of a harder grade of metal. Standard metal drill bits are available in diameters from 1 to 13 mm.
SKIL recommends wearing working gloves, safety eyewear, a dust mask, and hearing protection, as recommended in the user
manual, when working with power tools.
