1" x 18" Flat Chisel, General Purpose, SDS‑MAX

Execute controlled concrete breaking, conduit channeling, and masonry edging with the heavy-duty Makita D-36491 1" x 18" SDS-MAX General Purpose Flat Chisel. Forged from select high-grade steel and fully heat-treated for enhanced tensile resilience, this commercial chisel withstands heavy repetitive impact from powerful demolition breakers and rotary hammers without mushrooming or fracturing. Its 1-inch broad cutting blade delivers focused material displacement, making it ideal for clearing conduit raceways, chipping mortar, dressing concrete edges, and scaling thin surface layers. Featuring an extended 18-inch reach for working in deep slab trenches and footings, each chisel is sealed with an industrial anti-corrosion barrier to maintain long-term jobsite durability.

Key Features:

• Heavy-Duty SDS-MAX Fitment: Designed for full compatibility with all corded and cordless SDS-MAX rotary hammers and demolition breakers.

• Hardened High-Grade Steel: Industrial heat treatment hardens the striking face and edge, extending service life across abrasive masonry materials.

• 1" Controlled Edging Blade: Provides clean directional control for cutting straight channels, trimming slab edges, and knocking down high spots.

• 18" Extended Working Reach: Delivers reach and clearance around foundations, deep footings, and floor-level breakouts.

• Anti-Corrosion Surface Coating: Protective layer shields the raw steel against oxidation, humidity, and jobsite chemical contact.

• Multipurpose Demolition Performance: Optimized for channeling, light chipping, mortar joint removal, and surface dressing on brick, block, and concrete.
