Description
G-Metal HSS Drill Bits are drill bits made from high-speed steel for drilling holes in metal. High-speed steel is a tool-steel category widely used for twist drills because it keeps its hardness at the temperatures reached during drilling.
HSS bits are commonly used on mild and structural steel, and on softer metals such as aluminium. The material, the hole diameter and the drilling equipment decide which bit is the right one for the job.
Key Features and Benefits
Made for metal
HSS drill bits are a standard choice for drilling metal workpieces, from sheet and plate to structural sections.
Heat-tolerant tool steel
High-speed steel retains its hardness at higher working temperatures than plain carbon tool steel, which suits sustained drilling.
Matched to the drill
The shank has to suit the chuck of the drill or drill press, so the drilling equipment is part of the selection.
Chosen by hole size
The bit diameter sets the hole size, and larger holes call for more drill torque and a rigidly clamped workpiece.
Applications and Use Cases
HSS drill bits are used for:
- Drilling steel plate, sections and sheet in fabrication
- Pilot and clearance holes for bolts and fixings in steel
- Maintenance and repair drilling in workshops and on site
- Drilling aluminium and other non-ferrous metals
Technical Specifications
Key technical considerations when selecting the appropriate HSS drill bits for your application.
| Selection factor | What to consider | Details to confirm when ordering |
|---|---|---|
| Workpiece material | Mild steel, stainless steel and aluminium differ in hardness, so speed and feed change with the metal. | The metals to be drilled |
| Hole diameter | The bit diameter sets the hole size and the torque the drill must deliver. | The diameters required |
| Hole depth and bit length | Standard-length bits suit thin sections; deeper holes need bits with enough flute length. | The depth of hole and the clearance available |
| Shank and chuck | The shank must fit the drill chuck, and the chuck capacity limits the bit diameter. | The drill or drill press in use |
| Coating and point style | Surface treatments and point geometry vary between HSS bits and affect how a bit starts and wears. | Any coating or point preference |

Frequently Asked Questions
What are HSS drill bits used for?
They are used to drill holes in metal workpieces, including steel, and in softer metals such as aluminium.
Can HSS drill bits drill concrete?
No. Concrete and masonry call for drill bits made for that material, such as the G-Metal Concrete Drill Bits.
What helps match the right HSS drill bit?
The metal being drilled, the hole diameter and depth, and the drill or drill press in use.
How do I choose the diameter?
Choose the bit diameter from the hole size the job needs, and check that the drill chuck accepts the bit shank.
