Sealey HSS Drill Bits

Sealey HSS Drill Bits at Tooled-Up.com

Sealey HSS Drill Bits are sold as sets, so one case covers everything from small pilot holes to larger clearance holes in metal, timber and plastics. Tooled-Up.com stocks them in several steel grades and finishes, including the Sealey 11 Piece HSS Titanium Drill Bit Set, the Sealey 25 Piece HSS-Co Drill Bit Set and the Sealey 19 Piece HSS-G Drill Bit Set.

What sets the selection apart is the choice of specification. Standard HSS sets handle everyday jobs, titanium coated sets cope with harder metals and alloys, and HSS-Co sets are made for tougher materials such as stainless steel. There are also specialist sets, such as the Sealey 19 Piece Left Hand Spiral Drill Bit Set and the Sealey 17 Piece HSS and Masonry Drill Bit Set.

Key Features of Sealey HSS Drill Bits

• Titanium coating: reduces friction and resists heat, which allows faster drilling, cleaner holes and a longer working life in hard metals and alloys.
• HSS-Co (cobalt) steel: holds its edge at high temperatures, so it suits tougher, heat-generating materials such as stainless steel.
• HSS-G (ground) and HSS-R (roll forged) bits: precision ground bits give accurate, consistent cutting, while roll forged bits are a durable, economical choice for general workshop use.
• Edge ground tips: these help the bit start cleanly and reduce wandering on the surface.
• Left hand spiral bits: useful for drilling in reverse, for example to help free fasteners that are seized or snapped off.
• Organised cases: sizes are held in order, so you can find the right bit quickly and see what is missing.

Who Uses Sealey HSS Drill Bits?

Metalworkers, fabricators and welders use the titanium and HSS-Co sets for steel and alloy work. Mechanics and vehicle technicians value the left hand spiral set for broken bolts and studs. Joiners, maintenance engineers and plumbers can drill pilot and clearance holes in timber, plastics and thin metal, while the HSS and masonry set suits general site work where materials change from one hole to the next. The larger assorted sets also make sense for busy workshops, garages and DIY users who want a full range of sizes on hand.

Frequently Asked Questions

What is the difference between HSS and HSS-Co drill bits?

Standard HSS bits suit general drilling in softer metals, timber and plastics. HSS-Co contains cobalt, which resists heat better and makes it the stronger option for harder materials such as stainless steel.

Is a titanium coated drill bit worth choosing?

Yes, if you drill metal often. The coating reduces friction and heat, which helps the bit last longer and cut more cleanly. Sealey titanium sets are designed for hard metals and alloys.

When would I use a left hand spiral drill bit?

Left hand bits are used with the drill in reverse. They are handy for removing damaged or seized fasteners, as the drilling action can sometimes loosen the fixing itself.

Can I use HSS drill bits on masonry?

Standard HSS bits are not suitable for brick or concrete. For mixed jobs, the Sealey 17 Piece HSS and Masonry Drill Bit Set includes bits for both. Shop Sealey HSS Drill Bits at Tooled-Up.com to find the right set for your materials.
