Chisel (Flat) Irwin 20×250 mm SDS+ — 20 mm blade, 250 mm length

Flat chisel Irwin 20×250 mm SDS+ is a hand tool accessory for SDS+ rotary hammers and demolition hammers. It features a 20 mm wide blade and a total length of 250 mm, with an SDS+ shank for quick, secure attachment to compatible machines. The chisel provides a flat cutting edge intended for removal of tiles, mortar, plaster and other materials during demolition and renovation work.

Advantages

The chisel is made from hardened steel to withstand repeated impact and reduce wear. The SDS+ shank ensures fast, tool-free insertion and reliable retention in SDS+ hammer chucks. The 20 mm blade width offers a balance between concentrated force for breaking and sufficient surface area for scraping and material removal. Its 250 mm length gives adequate reach for most wall and floor demolition tasks while maintaining handling control.

How to use

Insert the SDS+ shank into the hammer chuck according to the tool manufacturer's instructions until it locks. Select the appropriate hammer function and impact energy for the substrate. Position the flat blade against the work surface and apply steady, controlled strikes with the rotary or demolition hammer. Move the chisel along the area to remove tiles, mortar or plaster, taking care to control depth and angle to avoid unwanted damage to underlying surfaces. Periodically inspect the blade for wear or deformation and replace if the cutting edge becomes excessively rounded or damaged.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, gloves and hearing protection. Match the chisel width to the task for efficient material removal, and avoid excessive side loading to prolong tool life. Store the chisel in a dry place to prevent corrosion.
