- The 17mm hex shank interface ensures a rock-solid, play-free connection to your demolition hammer, maximizing energy transfer from the tool to the work surface and minimizing operator fatigue during extended use — a critical advantage on large-scale demolition projects.
- At 400mm in total length, this flat chisel provides the reach needed to work in recessed areas, deep floor channels, and wall cavities where shorter bits simply cannot access, giving professionals the flexibility to tackle complex site conditions without switching tools.
- The wide, flat blade geometry is precision-ground to distribute impact force evenly across the cutting edge, making it exceptionally effective for tile removal, mortar scraping, and surface preparation — delivering clean, controlled results with minimal collateral damage to surrounding materials.
- Manufactured from high-grade alloy steel with a heat-treated tip, this chisel is engineered to withstand the repeated high-frequency impacts of professional demolition hammers without deforming, chipping, or losing its edge — ensuring consistent performance across thousands of working cycles.
- Designed for broad compatibility with SDS-max rotary hammers, demolition hammers, and chipping hammers, the 17x400 hex flat chisel integrates seamlessly into professional tool setups from leading brands, making it a versatile addition to any contractor's accessory kit.
- The flat chisel profile is ideal for hardened adhesive removal, paint stripping, and surface coating elimination on concrete, brick, and stone substrates — tasks that demand a tool capable of sustained impact without flexing or binding under load.
This chisel meets the quality and dimensional standards expected of professional demolition accessories and is supplied ready to use, with the hex shank pre-formed to fit standard demolition hammer chucks directly out of the box — no adapters or additional components required.
General Purchase & Comparison Queries
What is the Ideal Flat Chisel 17x400 Hex and what makes it different from a standard chisel?
The Ideal Flat Chisel 17x400 Hex (Model 17018) is a professional demolition hammer accessory designed for power tool use — not a hand chisel. Its 17mm hex shank locks directly into compatible demolition hammers and rotary hammers, while the 400mm length and broad flat blade are engineered to handle high-torque, high-frequency impacts that would destroy a conventional hand chisel. It is purpose-built for heavy-duty site work including concrete breaking, tile removal, and mortar scraping.
Is this chisel compatible with my demolition hammer or rotary hammer?
This chisel uses a 17mm hex shank, which is the standard interface for SDS-max demolition hammers, heavy-duty rotary hammers, and chipping hammers from most professional brands. Before purchasing, confirm that your tool accepts a 17mm hex shank accessory — this information is typically listed in your tool's manual or on the manufacturer's website. It is not compatible with SDS-plus or round-shank tools.
Why choose a 400mm flat chisel over a shorter version?
The 400mm length provides extended reach that shorter chisels cannot match — particularly useful when working in deep floor channels, wall recesses, or confined demolition zones where a compact bit would require awkward tool positioning. The longer shank also helps absorb and distribute vibration over a greater surface area, reducing stress concentration at the chuck interface during prolonged use.
Product-Specific and Usage Queries
What materials can the Ideal Flat Chisel 17x400 cut or break through?
This flat chisel is designed for use on concrete, brick, masonry, stone, and mortar. Its broad blade profile also makes it highly effective for ceramic and porcelain tile removal, stripping hardened adhesives and surface coatings, and cleaning mortar joints. It is not intended for cutting metal or wood — for those applications, a different chisel profile and tool type would be required.
How do I correctly insert and secure the hex shank chisel into my demolition hammer?
To fit the chisel, ensure your demolition hammer is switched off and unplugged or battery-removed. Retract the tool chuck collar, align the 17mm hex shank with the chuck opening, insert firmly until you feel it click or lock into place, then release the collar. Give the chisel a firm tug to confirm it is seated securely before operating. Always refer to your specific tool's manual for the correct insertion procedure, as chuck mechanisms vary by brand and model.
How should I maintain the flat chisel to extend its working life?
After each use, clean the shank and blade of concrete dust, mortar residue, and debris using a wire brush or dry cloth. Inspect the cutting edge for signs of deformation or chipping — a damaged edge reduces efficiency and can cause unpredictable behavior under impact. Apply a light coat of machine oil to the hex shank before storage to prevent corrosion. Store the chisel in a dry environment away from moisture. Do not use the chisel if the shank shows visible cracks or the blade is severely deformed.
Problem/Solution-Oriented Queries
The chisel keeps slipping or vibrating loose during use — what should I do?
If the chisel is slipping, first confirm that the 17mm hex shank is fully seated in the chuck and that the locking collar has engaged correctly. Check the chuck mechanism on your demolition hammer for wear — a worn chuck may no longer grip the shank firmly and may need servicing. Also inspect the shank itself for wear, burring, or deformation that could prevent a secure fit. Never operate a chisel that is not fully locked into the tool, as this creates a serious safety hazard.
The chisel tip is becoming blunt quickly — is this normal, and what can I do?
Some tip wear is normal with heavy use on hard concrete or reinforced masonry, but accelerated blunting can indicate that the tool's impact energy setting is too low (causing the chisel to grind rather than chip), or that the chisel is being used at an incorrect angle. Ensure you are applying consistent, firm pressure and working at the correct angle to the surface. If the tip has deformed significantly, the chisel should be replaced — a blunt or deformed chisel transfers energy inefficiently and increases operator fatigue and tool wear.
Can I use this chisel for precision work, or is it only suited for rough demolition?
While the Ideal Flat Chisel 17x400 is primarily designed for heavy-duty demolition and material removal, its broad flat blade can be used for controlled scraping and surface preparation tasks that require a degree of precision — such as removing individual tiles without damaging the substrate or cleaning mortar from brick faces. For very fine or detailed chiseling work, a narrower point or cape chisel profile would be more appropriate. Operator technique and tool speed settings play a significant role in achieving controlled results.
