Bosch HSS-G Twist Drill Bit, 5mm Diameter, 86 mm Overall

Introducing the series of HSS-G Drill Bits from Bosch. These high-performance drill bits are designed to give a very clean, accurate holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron malleable cast iron, non-ferrous metals and hard plastic. The HSS-G drill bits enable up to 40% faster drilling rates and 50% lower feed pressure than standard HSS bits, with a chisel edge and split point drill tip manufactured to DIN338. The bit's exposed 135-degree self-centring split-point tip combines active cutting and perfect centring without wandering, delivering maximum precision. The split-point tip also eliminates any need to pre-punch or pilot drill for up to 10 mm.

• Features self-centring split-point for excellent positional accuracy and hole quality
• 135° point angle design for maximum accuracy of application
• No pre-punch or pilot required
• Right-hand helical drill bits type N
• Precision ground for a faster drilling rate and lower feed pressure
• Spiral helix enables rapid swarf removal
• Suitable for drilling in alloyed and non-alloyed steel up to tensile strength of 900N/m2
• Suitable for both hand and machine use

• DIN338
• DIN1412C Quadruple Sharpening
• Bosch Standard Quality

These bits are ideal for fast drilling of a plug, anchor or clearance holes in a number of materials such as steel, plastic, wood, metal etc. This makes it an essential piece of kit to have if you work within the carpentry/construction/engineering industries to save time and money on being able to perform more efficiently when working with stubborn materials.

Can these drill bits be used with any SDS drill?
No, they are standard drills, will not fit into SDS chuck

What does jobber mean?
The word jobber specifies the length of the drill bit. This generally means the length of the entire drill bit itself is significantly longer for diameter it has. As an example, a mechanic drill bit will have a much shorter flute and therefore have a much smaller overall length.

What are HSS and HSS-G?
An acronym for High-speed steel, HSS is generally the go-to type of steel needed for drill bits due to their excellent heat resistance at high speeds. The HSS-G drills bits are additionally ground at the tip and along with their flutes. HSS-G drill bits are ideal for high-performance, professional application and are ideal for drilling into an alloy and non-alloy steel, non-ferrous metals, grey cast iron and malleable iron, sintered iron.

Work efficiently when creating openings into surfaces using this 5mm-diameter drill bit from Bosch. It has a chisel edge and a split point, enabling output at rates up to 40% faster and with 50% less feed pressure than regular HSS bits. This means the tool stays centered while drilling to ensure spot-on results. The unit has a 135° angle and is ground precisely to achieve a specific shape and sharpness, resulting in smooth and accurate cutting. Thanks to a right-hand helix, it rotates clockwise and is compatible with standard drill chucks and power tools.

• Spiral helix delivers efficient chip removal and prevents heat build-up during drilling
• Overall length of 86mm gives easy reach to narrow depths
• Made from high-speed steel to resist corrosion and impact for long-lasting use

• Machine repair shops
• Construction industry
• HVAC installation

You can use this drill bit with alloyed and non-alloyed steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics. This makes it a versatile workmate in numerous settings.
