Borenset DeWALT CASSETTA 29 st

The DeWALT CASSETTA 29-piece drill bit set provides a comprehensive selection of bits for drilling in alloyed steel and other common metals. The set covers sizes from 1 mm up to 10 mm, offering stepwise increments to match a wide range of hole diameters. Bits are manufactured to deliver consistent cutting performance and straight drilling, suitable for workshop and on-site tasks where precision and durability are required.

Advantages

The set offers a broad size range that reduces the need to change tools frequently and supports both small-diameter pilot holes and larger through-holes. Each drill bit is produced to maintain edge hardness and resist wear during repeated use in alloyed steel. The organized cassette keeps the bits in order for quick size selection, helping to improve workflow and minimise downtime.

Suitable for

• Drilling holes in alloyed steel and other metal components
• Workshop maintenance and metalworking tasks
• Professional tradespeople and domestic DIY projects requiring metal drilling
• Creating pilot holes for tapping or fastening

Key specifications

• Number of pieces: 29
• Material compatibility: alloyed steel and general metalwork
• Size range: 1 mm to 10 mm (incremental sizes included)
• Storage: labelled cassette for organised bit storage

How to use

Select the correct drill bit size for the hole diameter required and securely clamp the workpiece. Install the bit in the drill chuck and tighten according to the drill manufacturer’s guidance. Use appropriate cutting speeds and apply steady feed pressure; reduce speed and increase lubrication when drilling harder alloys to prolong bit life. After use, allow bits to cool, clean off debris, and return them to the cassette to keep sizes organised and protect cutting edges.

Recommendations

For best results when drilling alloyed steel, start with a smaller pilot hole and progressively increase to the final diameter. Use cutting fluid on harder materials and consult the drill’s speed table for optimal RPM settings to balance cutting efficiency and tool life.
