INGCO SDS-Max 18x300x25mm Professional Flat Demolition Chisel (High-Hardness Wear-Resistant Forging, Shock-Optimized Concrete Breaker)
Smash through structural reinforced concrete, chip away tough brick masonry walls, and channel out thick cement floorings effortlessly without bending your tool shafts. The INGCO DBC0222801 SDS-Max Flat Chisel is an elite demolition solution built explicitly to handle the punishing impact waves thrown out by heavy-duty commercial rotary hammers. Combining a massive 18mm cross-sectional body with a precision-ground 25mm flat cutting edge, this chisel concentrates your power tool’s raw joules of impact energy directly into the material face—giving demolition crews, masonry contractors, and renovation teams a fast, unyielding edge that maintains its apex across thousands of punishing blows.
Heavy-Impact SDS-Max Architecture & 25mm Flat Apex
Universal High-Torque SDS-Max Shank Fitment: Machined with an industry-standard SDS-Max drive configuration. This heavy-duty shank profile features specialized deep tracking and locking grooves engineered explicitly to anchor safely inside large-scale 5kg to 11kg+ demolition hammers, ensuring maximum kinetic shock transfer without loose power slipping.
Precision-Ground 25mm Flat Cutting Apex: Features a sharp, robust 25mm cutting boundary. This flat geometric profile acts like a structural wedge, making it perfectly calibrated for controlled directional fracturing—ideal for removing old tile mortar beds, scaling cement crusts, squaring off rough window/door cuts in concrete walls, and peeling away plaster layer matrices.
Optimized 300mm Medium-Reach Blueprint: Measuring 300mm ($12\text{ Inches}$) in total length, this bit offers an exceptional structural balance. It keeps the operator close enough to the work surface to maintain absolute positioning accuracy, while providing plenty of deep clearance to reach into thick masonry walls and floor slabs.
Advanced Micro-Grain Metallurgy & Shot-Peened Surface
Induction-Hardened Wear-Resistant Alloy Forging: Forged from high-grade structural tool steel alloy and processed through a computer-calibrated thermal hardening cycle. This creates a high-hardness outer layer combined with a highly elastic inner core that can absorb punishing percussive vibrations without developing micro-cracks or shattering.
Anti-Clogging High-Velocity Clearance Stem: The transition zone right behind the 25mm flat head is tapered to rapidly displace broken stone chunks and concrete dust away from the active impact point, keeping your visual path clear and preventing the chisel tip from binding or jamming inside deep wall channels.
Corrosion-Resistant Protective Finishing: The entire tool surface is shot-peened and coated with a light industrial shield to guard against moisture, outdoor rain splashes, and aggressive concrete chemical lime corrosion during storage.

Best Use Cases
Commercial Reinforced Concrete Demolition: The absolute daily benchmark accessory for construction laborers to break open structural concrete pillars, crack open floor slabs for utility pipe laying, and clear away overspilled foundation cement blocks.
Masonry Brick Wall Channeling & Chipping: Perfect for electrical and plumbing contractors to rapidly chisel out clean wiring conduit tracks and water pipe channels inside raw brick walls before plastering runs.
Industrial Mortar & Floor Tile Descaling: Ideal for interior renovation crews in Salem to scale away stubborn tile adhesives, peel up ancient marble setting beds, and descale rough concrete finishes.
E-Commerce Facility Floor Modding: An exceptional maintenance utility asset to break away old anchoring bolts, trench concrete lines for automated conveyor power tracking, and modify warehouse floor boundaries.
TK Pro Tip: SDS-Max demolition chisels are engineered to absorb incredible percussive forces, and maintaining proper tool lubrication and down-force tracking is the ultimate secret to preventing chuck wear and unlocking a lifetime of high-speed breaking! Never run your rotary hammer in high-speed rotational mode while using a flat demolition chisel. Ensure your power tool dial is locked firmly into “Chipping/Hammer Only” mode so the chisel drives strictly back and forth without spinning. When setting the bit into the tool chuck, always wipe the SDS-Max shank end completely clean of any site sand or masonry grit, and apply a generous dollop of high-temperature specialty chisel grease directly to the locking grooves. This lubrication minimizes metal-on-metal friction heating inside the tool’s nose holder, prevents the shank from binding under heavy loads, and dramatically extends the life of your rotary hammer’s internal anvil mechanism!
The TK Tools Promise
Verified: 100% original, factory-authentic INGCO industrial masonry gear—sourced directly and verified for genuine SDS-Max shank dimensions and true 18x300x25mm structural parameters.
Shank Precision & Concentric Straightness Bench Check: Because heavy demolition tools leave absolute zero room for alignment errors or chuck jams, our dedicated technical desk in Salem manually unboxes every single flat chisel bit, measures the groove tracking depths under digital micrometer gauges, inspects the 25mm flat apex for absolute geometric symmetry under intense lighting, and verifies the axial straightness of the 18mm shaft before approving the plastic hanger pack for warehouse dispatch to guarantee vibration-free breaking right out of the box.
Fast & Safe Delivery: Wrapped securely inside custom shock-absorbent multi-layer cushioning and shipped rapidly from our main central hub straight to your project site gate door, retail store counter, or industrial field office locker.
