Jigsaw Blade Bosch EXPERT S1141HM for Aerated Concrete, model 2608900408

Bosch EXPERT S1141HM jigsaw blade for aerated concrete is a T-shank blade engineered for use with reciprocating jigsaws that accept T-shanks. The blade combines a tooth geometry and hardened tooth material designed to cut aerated or cellular concrete with improved cutting speed and reduced clogging. It is intended for construction and renovation tasks where accurate cuts in aerated concrete panels, blocks and lightweight masonry are required.

Advantages

The blade's hardened tooth edges and spacing optimise chip removal when cutting porous concrete, reducing binding and heat build-up. A slim, rigid blade body provides stable guidance and straight cuts, while the standard T-shank ensures fast, secure mounting in compatible jigsaws. The design balances cutting speed and service life for common on-site applications.

Suitable for

• Cutting aerated concrete panels and blocks
• On-site renovation and construction adjustments
• Creating openings for ducts, pipes and window frames in lightweight masonry
• Trimming aerated concrete to size before installation

Key specifications

• Blade type: T-shank jigsaw blade
• Material: hardened tooth material suited for masonry-like porous concrete
• Tooth geometry: designed for aggressive cutting and chip evacuation in aerated concrete
• Intended material: aerated (cellular) concrete and lightweight masonry
• Typical use: construction and renovation cutting tasks

How to use

Fit the T-shank blade securely into a compatible jigsaw according to the tool manufacturer's instructions and ensure the blade clamp locks fully. Select a moderate cutting speed and allow the blade to progress steadily through aerated concrete without forcing; excessive feed pressure can cause chipping or premature wear. Where possible, support panels to minimise vibration and obtain a straight, controlled cut. Replace the blade when cutting performance decreases or if teeth are visibly worn or damaged.

Recommendations

Wear appropriate personal protective equipment including eye protection, dust mask and hearing protection when cutting aerated concrete. Use dust extraction or local ventilation to reduce airborne particles. For finer finishes, make a preliminary shallow cut to define the line and complete the cut with steady feed. Store blades dry and keep them free from corrosive substances to maintain performance.
