⚡ At a Glance
  • Cutting Power: 850W motor delivering a 12,000 rpm no-load speed with a 115mm disc for tight spaces
  • Best for: DIY enthusiasts and tradespeople tackling cutting, grinding and polishing around the house
  • Not ideal for: Heavy industrial applications that require larger disc diameters and continuous high-duty use

An 850W motor pairs with a compact 115mm disc to handle cutting, grinding and polishing. Supplied accessories and safety features support everyday workshop and DIY use.


Controlled Cutting in Tight Spaces - with a 115mm disc and 2-position side handle

The smaller 115mm disc reduces the tool's profile while the auxiliary side handle locks into two positions for improved leverage. Spindle lock enables quick disc changes without awkward handling.

Easier access to confined areas such as around pipework and tight corners, allowing precise cuts and neater finishing with less fumbling.

Fast Material Removal - thanks to an 850W motor and 12,000 rpm no-load speed

High motor power combined with a rapid no-load speed increases abrasive throughput, letting cutting and grinding discs clear material more quickly. The power level suits a variety of disc types for different tasks.

Quicker cuts and more efficient rust or paint removal shorten job times on metal and masonry work, useful for both repair and refurbishment.

Safer Operation - with disc safety cover and accidental restart prevention switch

A protective disc cover shields the user from sparks and debris while an accidental restart prevention switch blocks unexpected motor start after power interruptions. The spindle lock also secures the disc during maintenance.

Reduced risk of injury and fewer interruptions while working, providing greater confidence during tougher tasks and when changing accessories.
