Key Features of Bosch Professional HSS Drill Bits

Bosch Professional HSS drill bits incorporate several distinctive features that set them apart from standard offerings:

Premium HSS Metallurgy: Manufactured from high-grade high-speed steel alloys that maintain hardness and cutting performance even at elevated temperatures generated during drilling. The precise composition ensures optimal balance between hardness for wear resistance and toughness to prevent brittle failure.

Precision Ground Cutting Edges: Each drill bit features accurately ground cutting edges and point angles that ensure true running and reduced walking when starting holes. This precision grinding delivers cleaner entry, more accurate hole positioning, and reduced burr formation on breakthrough.

Optimised Flute Design: The spiral flutes are engineered to provide efficient chip evacuation, preventing chip packing that can cause overheating and premature wear. The flute geometry also contributes to straight hole drilling by balancing cutting forces.

Advanced Coating Options: Many Bosch Professional HSS drill bits feature surface treatments such as titanium nitride coating, which provides enhanced wear resistance, reduces friction, and helps prevent material adhesion to the cutting edges. These coatings significantly extend tool life, particularly in demanding applications.

Split-Point Technology: Selected Bosch Professional HSS bits incorporate split-point geometry that eliminates the need for centre-punching, provides immediate bite on contact, and reduces the thrust force required for drilling. This feature is particularly valuable when drilling thin materials or working with hardened steels.

Cylindrical Shank Design: Precision-manufactured shanks ensure secure chuck grip and minimal runout, contributing to accurate drilling and extended bit life by reducing vibration and uneven wear.

Popular Bosch Professional HSS Drill Bits

The Bosch Professional HSS drill bits range at Tooled-Up encompasses various product types designed for specific applications:

HSS-G (Ground) Drill Bits: The standard range for general-purpose metal drilling, featuring precision-ground geometry suitable for steel, cast iron, non-ferrous metals, and plastics. Available in individual sizes and comprehensive sets covering the most commonly used diameters from 1mm to 13mm and beyond.

HSS-TiN Coated Drill Bits: Featuring titanium nitride coating for enhanced performance, these bits offer up to three times the life of uncoated HSS bits when drilling harder materials. The gold-coloured coating reduces friction and heat buildup, making them ideal for stainless steel and other challenging materials.

HSS-R (Rolled) Drill Bits: Cost-effective solutions for general drilling tasks, HSS-R bits are manufactured using a rolling process that creates the flutes. While slightly less precise than ground bits, they represent excellent value for less critical applications.

HSS-Co (Cobalt) Drill Bits: For the most demanding applications, Bosch Professional's cobalt-alloyed HSS drill bits provide superior heat resistance and wear performance when drilling hardened steels, stainless steel, and high-temperature alloys.

Extra-Long Series HSS Bits: Designed for deep drilling applications where standard jobber-length bits cannot reach, these extended-length drill bits maintain the accuracy and performance expected from Bosch Professional tools.

Metal Drill Bit Sets: Comprehensive sets housed in durable storage cases, providing a complete range of sizes for workshop or mobile use. These sets represent excellent value and ensure the right size is always at hand.

Safety and Compliance

When using Bosch Professional HSS drill bits, adherence to proper safety practices is essential for preventing accidents and achieving optimal results. Always wear appropriate personal protective equipment including safety glasses or face shields to protect against flying metal chips, which can be sharp and hot. Work gloves should be avoided during drilling operations as they present an entanglement risk with rotating tools.

Ensure workpieces are securely clamped before drilling, as HSS drill bits can grab material, particularly during breakthrough, causing it to spin dangerously. When drilling deeper holes, periodically withdraw the bit to clear chips and apply appropriate cutting fluid to reduce heat buildup and extend bit life. Never attempt to stop a spinning drill bit with your hand—allow it to come to a complete stop naturally.

Bosch Professional HSS drill bits should be used at appropriate speeds for the material and bit diameter being used. Excessive speed can cause overheating and rapid wear, while insufficient speed may result in work hardening of the material and premature bit failure. Always inspect drill bits before use for damage such as chipped cutting edges or bent shanks, and replace worn bits promptly to maintain drilling accuracy and safety.

In accordance with HSE guidance for metalworking operations, ensure adequate ventilation when drilling, particularly when using cutting fluids, and dispose of metal swarf safely to prevent cuts and injuries. Store drill bits properly in their cases or indexed storage to protect cutting edges and prevent accidental injury.

Frequently Asked Questions

What's the difference between HSS-G, HSS-R, and HSS-Co Bosch Professional drill bits?

HSS-G (Ground) bits are precision-ground for accuracy and superior performance in professional applications. HSS-R (Rolled) bits are manufactured through a rolling process, making them more economical for general use but slightly less precise. HSS-Co (Cobalt) bits contain cobalt alloy, providing enhanced heat resistance and wear performance for drilling hardened materials and stainless steel. For most professional metalworking, HSS-G represents the optimal balance of performance and value.

Can I use Bosch Professional HSS drill bits in wood or masonry?

While HSS drill bits are specifically designed for metal, they can drill wood, though wood-specific bits will perform better and last longer. However, HSS bits should never be used in masonry, concrete, or brick, as these materials will rapidly destroy the cutting edges. For masonry applications, always use carbide-tipped masonry bits or SDS drill bits designed for impact drilling.

How can I extend the life of my Bosch Professional HSS drill bits?

Use appropriate drilling speeds for the material and bit diameter—slower speeds for larger diameters and harder materials. Apply cutting fluid or lubricant when drilling steel and stainless steel to reduce friction and heat. Ensure your drill chuck grips the bit shank securely to prevent slippage. Periodically withdraw the bit during deep drilling to clear chips. Store bits properly to protect cutting edges, and sharpen or replace bits when they become dull rather than forcing them to cut, which accelerates wear.

What speed should I use when drilling with Bosch Professional HSS bits?

Drilling speed depends on both the bit diameter and the material being drilled. As a general guide, smaller bits require higher speeds while larger diameters need slower speeds. Mild steel typically requires speeds between 600-3000 RPM depending on bit size, while stainless steel requires roughly half that speed. Aluminium and softer metals can tolerate higher speeds. Most Bosch Professional HSS bit packaging includes speed recommendations, and the bits perform best when used within these parameters.

Are Bosch Professional HSS drill bits suitable for drilling stainless steel?

Yes, Bosch Professional HSS drill bits can drill stainless steel, though it's a demanding application that requires proper technique. HSS-Co (cobalt) or HSS-TiN coated bits provide the best performance for stainless steel due to their enhanced heat resistance. Use slower speeds than you would for mild steel, apply steady feed pressure, and always use cutting fluid to reduce heat buildup. Stainless steel work-hardens easily, so maintain constant feed pressure—hesitation can harden the material and make further drilling extremely difficult.
