Bosch Professional HSS Drill Bits

Bosch Professional HSS Drill Bits at Tooled-Up.com

Bosch Professional HSS Drill Bits are high-speed steel bits for drilling metal accurately and efficiently. Tooled-Up.com stocks them as PointTeQ twist drill sets, step drill bits and combined drill and screwdriver sets, so there is a Bosch option for sheet metal, brackets, steel fixings and general fabrication work.

The PointTeQ sets are the core of the selection. They combine a 135-degree tip angle with a self-centring design that stops the bit wandering at the start of each hole, so you can drill without centre-punching first. The sets cover diameters from 1mm up to 10mm in the 10 piece set, and larger sets extend the choice of sizes for workshop or van use.

Beyond twist drills, the Bosch Professional selection includes HSS, HSS-TiN and HSS-AlTiN step drill bit sets for sheet metal and thin materials. It also includes Impact Control hex shank sets for use with impact drivers. Browse the full Bosch Professional HSS Drill Bits category to match the bit type to the job.

Key Features of Bosch Professional HSS Drill Bits

• PointTeQ tip geometry: The 135-degree tip angle and self-centring point locate accurately on the first contact. This reduces wandering and speeds up drilling.
• Reduced friction and heat: The PointTeQ geometry increases the drilling rate and cuts friction and heat build-up, which helps the bits stay sharper for longer between replacements.
• High-speed steel construction: HSS holds its cutting edge at the temperatures generated when drilling metal, making these bits well suited to steel and other tough materials.
• Step drill design: A single step bit drills a range of hole diameters in thin material, so you do not have to swap bits. Plain HSS, TiN-coated and AlTiN-coated versions suit different levels of wear and workload.
• Impact Control hex shanks: Designed for use in impact drivers, these sets allow quick bit changes and a secure fit in the driver's chuck.
• Drill and screwdriver combinations: Mixed sets for metal put the drilling and fastening bits in one case, which saves carrying separate sets from job to job.

Who Uses Bosch Professional HSS Drill Bits?

These bits suit anyone who regularly drills metal on site or in the workshop:

• Fabricators and engineers: Accurate, repeatable holes in steel plate, angle and sections.
• Electricians: Drilling trunking, steel enclosures, cable trays and mounting brackets. Step bits are handy for cleanly sizing holes in thin enclosures.
• Plumbers and heating engineers: Fixing points for brackets and clips, and pilot holes in metal pipework supports.
• Roofers and cladders: Sheet metal drilling and fixings, particularly where a hex shank set pairs with an impact driver.
• Vehicle technicians and maintenance engineers: Repair work on panels, chassis and machinery.
• Serious DIYers: A PointTeQ set or a combined drill and screwdriver set covers most household metalworking jobs.

Popular Bosch Professional HSS Drill Bits

PointTeQ HSS Drill Bit Sets

Available from compact sets through to extended sets, the PointTeQ sets are the all-round choice for drilling metal. Smaller sets suit a toolbag. Larger sets give a full spread of diameters for workshop use. Each one benefits from the self-centring tip and 135-degree point angle.

HSS Step Drill Bit Sets

These come in plain HSS, HSS-TiN and HSS-AlTiN versions. They are ideal for enlarging holes progressively in sheet metal, panels and enclosures. The coated versions add wear resistance for heavier or more frequent use.

Impact Control Hex Shank HSS Sets

The Impact Control metal drill bit sets, including the hex shank HSS set, are made for impact driver users who want fast bit changes and reliable performance in metal.

Drill and Screwdriver Bit Sets for Metal

The 35 piece sets combine HSS drill bits with screwdriver bits, including an impact version. They suit installers who drill a pilot hole and drive the fixing in the same visit. Shop Bosch Professional HSS Drill Bits at Tooled-Up.com to compare set contents and sizes.

Safety and Compliance

Wear safety glasses to protect against hot, sharp swarf. Do not wear loose gloves near a rotating bit. Clamp the workpiece securely, because the bit can grab on breakthrough and spin thin sheet. Use a pilot hole for larger diameters, and select a sensible speed for the material: slower for larger bits and stainless steel.

If you use cutting fluids, follow COSHH guidance and the product's safety data. Make sure corded drills run from a correctly rated 240v supply, ideally through an RCD on site. Check bits for chipped tips or bent shanks before use. Follow HSE guidance on vibration and dust, and clear swarf carefully rather than by hand.

Frequently Asked Questions

What is the benefit of PointTeQ drill bits?

PointTeQ bits have a 135-degree tip angle and a self-centring point. They start accurately without a centre punch, drill faster and generate less friction and heat, which helps the bit stay sharp.

What size range do the PointTeQ sets cover?

The 10 piece PointTeQ set covers 1mm to 10mm. Other sets in the category offer different size selections, so check the contents against the holes you drill most.

When should I choose a step drill bit instead of a twist drill?

Choose a step drill for thin sheet metal, panels and enclosures, where you need clean holes in several sizes. Use a twist drill such as a PointTeQ bit for thicker material and standard fixing holes.

Can I use these bits in an impact driver?

Yes, if you choose a set designed for it. The Impact Control hex shank sets and the Impact HSS drill and screwdriver set are made for impact driver use. Standard round shank bits are better suited to a drill chuck.

How do I get the best life from HSS drill bits in steel?

Use a moderate speed, steady pressure and cutting fluid where appropriate. Clear swarf regularly and avoid forcing a dull bit. Coated step bits and the PointTeQ geometry also help reduce wear and heat.
