## Summary description

Conical HSS drill bit by Irwin, diameter 30 mm (MPN 10502458). High-speed steel construction suitable for drilling metals and other materials compatible with HSS tooling. Conical geometry enables step drilling or enlarging holes; intended for use with drills and drill presses. Useful for metalworking, maintenance, and fabrication tasks requiring a 30 mm conical hole.

## Long description

Irwin HSS conical drill bit, 30 mm diameter, is a single-piece high-speed steel tool designed for creating or enlarging holes with a stepped or tapered profile. The conical geometry allows controlled removal of material and smooth progression between diameters, making it suitable for drilling metals and other materials compatible with HSS tooling. The bit is intended for use in hand drills and drill presses where a 30 mm conical hole or step is required for fabrication, maintenance or repair tasks.
Advantages
The HSS construction provides good hardness and heat resistance for extended cutting life under typical drilling speeds. Conical (step) geometry permits progressive cutting and reduces the need for multiple separate sizes, enabling efficient enlarging of existing holes or forming tapered entries. The single-piece design offers rigidity and straightforward mounting in standard chucks or drill holders. Overall, the tool balances durability and ease of use for metalworking applications.
Suitable for
 Drilling and enlarging holes in carbon steel and alloy steels
 Creating stepped or tapered entries in metal plates
 Maintenance, fabrication and repair tasks requiring a 30 mm conical hole
 Use with bench drill presses and hand drills compatible with HSS bits
Key specifications
 Material: high-speed steel (HSS)
 Geometry: conical/step profile
 Nominal diameter: 30 mm
 Intended mounting: standard drill chucks and drill press holders
 Primary applications: metalworking and general fabrication
How to use
Secure the drill bit in an appropriate chuck or holder ensuring proper concentricity and tight clamping. Select a suitable cutting speed and feed for the workpiece material; use cutting fluid when drilling metals to reduce heat and extend tool life. Start the hole at low speed to establish the center, then apply steady pressure while allowing the conical profile to progress through the material. Withdraw periodically to clear chips and reapply coolant as needed. When enlarging existing holes, align the bit carefully to avoid eccentric cutting.
Usage recommendations
For best results when working with steel or other hard materials, use cutting fluid, moderate speeds appropriate for HSS, and secure workpiece clamping. Inspect the bit for wear or damage before use and replace when cutting performance degrades to maintain hole quality and safety.
