Qinding Machinery’s Chisels category is centered on a professional flat masonry chisel designed as an SDS Max rotary hammer attachment. The current product uses premium 40Cr alloy steel, a wide flat tip of approximately 1 inch or 25 mm, heat treatment, an anti-corrosion coating and a listed hardness of HRC 48–52. It is intended for concrete, brick, stone, masonry, tile removal, rust stripping, scale removal and related construction or industrial surface-preparation work.
This product should be selected differently from a handheld wood chisel or manual cold chisel. The shank is specifically listed as SDS Max, meaning compatibility with the rotary hammer is a primary requirement. For B2B buyers, the most important questions are therefore tool-holder standard, tip width, target material, required removal rate and whether the task is chipping, scraping or breaking.
Renovation and demolition often require removal rather than drilling. Old tile, adhesive, mortar, plaster, concrete projections, rust and coatings may need to be chipped or scraped away from a surface. A pointed chisel concentrates impact into a small area, but a flat chisel distributes force across a wider cutting edge. Qinding Machinery’s 25 mm flat tip is intended to support controlled material removal over a broader contact area.
The main purchasing risk is shank mismatch. An SDS Max chisel will not be appropriate for every rotary hammer system. Buyers must confirm that the machine accepts SDS Max accessories before ordering. The product page explicitly states compatibility with SDS Max rotary hammers.
| Specification | Current Product | Procurement Relevance |
|---|---|---|
| Product type | Flat masonry / concrete chisel | Designed for chipping, scraping and removal rather than drilling. |
| Shank | SDS Max | Rotary hammer must use the same accessory standard. |
| Tip | Wide flat chisel tip | Suitable for broader material-removal contact. |
| Tip width | 1 inch / approximately 25 mm | Relevant to removal width and surface control. |
| Material | 40Cr alloy steel | Selected for impact strength and wear resistance. |
| Hardness | HRC 48–52 | Balances edge durability with impact loading. |
| Surface treatment | Heat-treated, anti-corrosion coating | Supports wear and storage performance. |
| Applications | Concrete, brick, stone, masonry, tile, rust and scale | Choose according to the substrate and removal objective. |
A flat chisel is suited to scraping, scaling and removing layers across a defined width. A point chisel is more suitable when the operator needs concentrated penetration into a small area. A handheld chisel used with a manual hammer provides more control for smaller jobs but does not receive continuous power from a rotary hammer. Qinding Machinery’s current product is specifically a powered SDS Max attachment, so it should be positioned for compatible machine-assisted construction work.
For distributors, keyword coverage can include SDS Max chisel, concrete chisel, masonry chisel, flat chisel bit, rotary hammer chisel, tile removal chisel, demolition chisel and 40Cr chisel supplier.
The product page lists concrete, mortar and plaster removal during wall and floor renovation. A flat chisel can remove raised areas or break surface material after the rotary hammer applies impact. Contractors should select the working angle according to the material and avoid driving the tool too deeply when the objective is to remove only the surface layer.
Brick and stone demolition is another listed application. The wide tip can help remove mortar or break sections where controlled chipping is needed. For heavy structural demolition, buyers should evaluate whether the tool and rotary hammer are sized appropriately for the job rather than expecting one accessory to replace larger demolition equipment.
Tile removal is a strong application for a flat chisel because the operator can work between the tile and substrate or scrape adhesive from the surface. The product page also lists removal of old paint, rust and scale from metal surfaces. These jobs use the same general principle—impact drives the flat edge under or through unwanted material—but the operator should adjust angle and force to avoid unnecessary damage to the base material.
Before installation, confirm that the rotary hammer is an SDS Max model. Clean the shank and inspect the retaining area. Insert the chisel according to the machine manufacturer’s instructions and confirm it locks properly. The product page states that the chisel fits SDS Max rotary hammers, so the buyer should not treat it as a universal SDS Plus or hex-shank accessory.
During operation, maintain control with both hands on the rotary hammer, keep the flat tip at an appropriate angle to the surface and avoid excessive side loading that can bend the chisel. The work area should be clear of hidden services and loose debris.
For masonry impact work, review the 40Cr SDS Max flat concrete and masonry chisel. For manual heavy striking around demolition and maintenance work, the one-piece forged octagonal hammer provides 2–4 LB weight choices. Once material has been loosened, the 18-inch forged demolition pry bar with nail-puller slot can be used for leverage and separation tasks.
After use, remove dust and debris from the tool, check the shank for wear and inspect the flat edge for excessive rounding or chipping. The product page recommends cleaning, light oil for rust protection and dry storage. Because the chisel is an impact accessory, buyers should treat wear as part of the tool’s operating life and keep replacement units available for high-volume demolition work.
For B2B sourcing, specify the SDS Max shank requirement, tip width, application, expected volume and quantity. Contractors may want cartons of identical 25 mm flat chisels for tile or concrete projects; distributors may want branded packaging or a mixed accessory assortment. If custom dimensions are required, provide a drawing or exact tip/shank specification instead of only asking for “custom chisels.”

1. What material is used for the current flat chisel?
The technical table lists premium 40Cr alloy steel with heat treatment and anti-corrosion coating.
2. What is the tip width?
The product page lists a 1-inch, approximately 25 mm, wide flat chisel tip.
3. Which rotary hammers are compatible?
The product is specified for SDS Max rotary hammers.
4. What applications are listed?
Concrete, brick, stone, masonry, tile removal, rust stripping and scale removal are listed among the primary uses.
5. How should the chisel be maintained?
Remove debris after use, inspect the shank and edge, apply light anti-rust oil when appropriate and store the tool dry.
For a renovation contractor, chisel quantity should reflect project area, substrate hardness and expected wear rather than only the number of rotary hammers. Keeping spare chisels on site prevents a worn edge or damaged shank from stopping work. Distributors can also reduce confusion by labeling SDS Max clearly and separating these products from SDS Plus accessories, since shank compatibility is a decisive specification.
