Jargon Buster

• HSS (High-Speed Steel): A hardened steel alloy designed to withstand the high temperatures generated during drilling. HSS bits are suitable for drilling metal, wood, and plastic. HSS-R refers to rolled steel, whilst HSS-G indicates ground steel for greater precision and longer cutting life.
• Titanium Coating: A surface treatment applied to drill bits that increases hardness, reduces friction, and extends bit life significantly. Titanium-coated bits maintain their sharpness longer and can drill faster than uncoated alternatives, making them ideal for professional use.
• SDS Plus: A specialised shank system designed for rotary hammer drills, primarily used for masonry drilling. SDS (Special Direct System) allows for quick bit changes without tools and provides superior impact transmission for drilling concrete and brick on construction sites.
• Auger Bits: Long drill bits with a helical screw thread design, specifically engineered for deep drilling in timber. The screw tip pulls the bit through the wood whilst the spiral flutes efficiently remove waste material, essential for carpentry and joinery work.
• Step Drill: A conical drill bit with stepped diameter increases, designed to drill multiple hole sizes with a single bit. Particularly useful for sheet metal and electrical installation work, allowing sparkies to create various sized holes without changing bits.
• PointTeq Technology: Bosch's precision tip design that provides exact drilling starts without the bit walking across the material surface, improving accuracy and reducing user effort, particularly valuable for repetitive professional applications.

How to Choose the Right Drill Bit Sets

Material Application: Identify which materials you'll predominantly be drilling. Wood-specific sets feature flat bits and auger bits, masonry sets include carbide-tipped bits, whilst metal drilling requires HSS or cobalt bits. Universal sets provide versatility across multiple materials, making them ideal for general tradespeople who encounter varied work.

Bit Quality and Coating: Professional users should invest in HSS-G (ground) or titanium-coated bits for enhanced durability and precision. These maintain sharpness longer and deliver cleaner holes, reducing the need for frequent replacements. Budget-conscious DIYers may find HSS-R (rolled) bits adequate for occasional use, whilst contractors benefit from the extended lifespan of premium options available from Tooled-Up.

Size Range and Quantity: Consider the hole sizes you commonly drill. Comprehensive sets offering 1mm increments provide maximum flexibility, whilst focused sets with fewer, strategically-sized bits may suit specific trades. Check the maximum diameter included matches your typical requirements – sets range from compact 6-piece collections to extensive 105-piece kits.

Shank Type Compatibility: Ensure the shank type matches your drill chuck. Standard round shanks fit most drills, hex shanks suit quick-change chucks and impact drivers, whilst SDS Plus bits require compatible hammer drills. Many modern sets feature hex shanks for versatility, particularly useful when working with 240v cordless drills that have quick-change systems.

Storage Case Quality: Professional tradespeople benefit from robust cases with clear size markings and secure closures that withstand site conditions. Indexed cases help quickly identify missing bits, whilst compact designs are easier to transport in tool bags or vans. Bosch Professional sets typically feature durable cases designed for daily professional use.

Brand Reputation: Established brands like Bosch Professional, Bahco, and Blue Spot Tools invest in manufacturing quality and metallurgy. Professional-grade sets typically offer better concentricity, harder materials, and more precise grinding, resulting in straighter holes and longer lifespan compared to unbranded alternatives.

Safety Information

Always wear appropriate personal protective equipment when using drill bits, including safety glasses or goggles to protect against flying debris and metal swarf. Secure workpieces properly using clamps or vices rather than holding by hand, as drill bits can grab and spin materials unexpectedly, particularly when breaking through surfaces. Follow HSE guidance for power tool use, particularly on construction sites where additional safety protocols may apply.

Inspect drill bits before use for damage, cracks, or excessive wear. Damaged bits can shatter during operation, creating dangerous projectiles. Ensure bits are correctly and securely fitted in the drill chuck, tightening all jaws evenly. Never exceed the maximum recommended speed for a particular bit type and diameter, as excessive RPM can cause overheating and failure.

When drilling metal, use appropriate cutting fluid and allow bits to cool between drilling operations to prevent temper loss and premature wear. Be aware of hidden electrical cables, gas pipes, and water pipes before drilling into walls, floors, or ceilings – use a cable detector to scan the area first. This is particularly critical when working with 240v mains-powered tools near potential electrical hazards.

Store drill bits safely in their provided cases with sharp edges protected. Keep sets away from moisture to prevent rust formation, particularly on uncoated HSS bits. Replace worn or damaged bits promptly rather than forcing them to continue working, as dull bits require excessive pressure and increase the risk of accidents.

Frequently Asked Questions

What's the difference between HSS-R and HSS-G drill bits?
HSS-R (Rolled) bits are manufactured by rolling the steel, making them more economical and suitable for general-purpose drilling. HSS-G (Ground) bits are precision-ground after hardening, resulting in superior accuracy, sharper cutting edges, and longer lifespan. Professional tradespeople typically prefer HSS-G for critical work, whilst HSS-R suits DIY applications adequately.

Can I use wood drill bits on metal or masonry?
No, drill bits are specifically designed for particular materials. Wood bits have different cutting geometries and aren't hardened sufficiently for metal or masonry. Using them on inappropriate materials will quickly damage the bit and produce poor results. Always match the bit type to your material – use HSS for metal, carbide-tipped for masonry, and brad point or flat bits for wood.

How do I know when drill bits need replacing?
Replace drill bits when you notice excessive heat generation, burning smells, slow drilling progress despite adequate pressure, wandering or walking across material surfaces, or rough, torn holes instead of clean cuts. Visible damage such as chipped cutting edges, bent shanks, or worn flutes also indicate replacement is necessary. Professional users often replace bits before complete failure to maintain work quality.

Are expensive drill bit sets worth the extra cost?
For professional tradespeople, premium drill bit sets from brands like Bosch Professional offer significantly better value over time due to extended lifespan, superior cutting performance, and reduced downtime. The better metallurgy and precision manufacturing justify higher initial costs. DIY users with occasional needs may find mid-range sets provide adequate performance at reasonable prices, though the cheapest sets often prove false economy due to rapid wear.

What size drill bit set do I need for general use?
A comprehensive set containing bits from 1mm to 13mm in 0.5mm or 1mm increments covers most general applications for tradespeople and DIY enthusiasts. Many users find a mixed set containing wood, metal, and masonry bits most versatile. Professional specialists may prefer focused sets optimised for their primary material alongside a smaller universal set for occasional varied work.
