Is HSS G better than HSS R?
HSS-R Drill Bits – the “R” stands for Roll Forged. HSS-G Drill Bits – HSS-G drill bits are ground, and typically provide better performance than HSS-R bits. As a consequence they are usually more expensive to buy.
What does HSS mean in drill bits?
High-Speed Steel
DRILL BIT MATERIALS High-Speed Steel (HSS) is a popular material good for drilling into soft steels as well as wood and plastic. IT’s an economical solution for most maintenance drilling applications.
What is HSS G?
The HSS Twist Drill Bit Ground is for drilling through metal with maximum precision. This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges. …
Is titanium harder than HSS?
The titanium nirtride (gold colored) coating on drills fills in the microscopic pores in the HSS making the chips clear better. It also provides a very thin but harder surface. This allows the drill to stay sharper longer and run at faster speeds with the same material being drilled.
What are Brad point drill bits used for?
Brad point drill bits are specially designed to drill and bore clean holes in hard and soft woods without wandering. These drill bits have been designed with a center pin as seen in the images below and on the right. A Brad Point Drill Provides a clean, straight, and accurately sized hole in wood.
Can you use HSS drill bit masonry?
High-speed steel (HSS) drill bits can drill wood, fiberglass, polyvinyl chloride (PVC) and soft metals such as aluminum. Carbide-tipped drill bits stay sharp much longer than steel, HSS or titanium bits. They’re effective for drilling tile and masonry.
What are HSS titanium drill bits used for?
Titanium-coated HSS drill bits produce less friction. They’re tougher than basic HSS bits and stay sharp longer. They work for drilling wood, metal, fiberglass and PVC.
What’s the hardest metal to drill through?
Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials.
