The Drill Bit AWTools SDS Max 40×400×540 mm (AW43879) is compared with several alternative models from the same manufacturer and product line: AWTools SDS Max 32 x 400 x 540 mm (AW43864), AWTools SDS‑MAX 20 x 400 x 540 mm (AW43829), AWTools SDS MAX 30 x 400 x 540 mm (AW43859), AWTools SDS Max 38 x 400 x 540 mm (AW43874), and SDS Max AWTools 35 x 400 x 540 mm (AW43869). All these products share a common design: an SDS Max shank with a square contact profile, an identical working length of 400 mm, an overall length of 540 mm, and a primary purpose for heavy-duty construction and renovation drilling in concrete and masonry. The core practical difference lies in the drilling diameter, which determines the size of the holes created.
⚙️ The specifications comparison table below compares key characteristics such as drilling diameter, shank type, working and overall length, as well as the practical purpose of each model to help evaluate their capabilities in construction tasks.
| Parameter | AWTools 40×400×540 mm | AWTools 32 x 400 x 540 mm | AWTools 20 x 400 x 540 mm | AWTools 30 x 400 x 540 mm | AWTools 38 x 400 x 540 mm | AWTools 35 x 400 x 540 mm | Practical Conclusion |
|---|
| Diameter | 40 mm | 32 mm | 20 mm | 30 mm | 38 mm | 35 mm | A larger drill diameter allows for wider holes for utilities and heavy anchors, whereas smaller diameters are ideal for standard fasteners. |
| Shank | SDS Max, square | SDS Max, square | SDS MAX, square | SDS MAX, square | SDS Max, square | SDS Max, square | All models feature the same shank type, ensuring secure mounting and torque transmission in compatible rotary hammers. |
| Working and overall length | 400 / 540 mm | 400 / 540 mm | 400 / 540 mm | 400 / 540 mm | 400 / 540 mm | 400 / 540 mm | Identical drilling depth allows all items to penetrate deep structural walls and masonry with equal reach. |
| Material and application | Concrete and masonry | Concrete and masonry | Concrete and masonry | Concrete and masonry | Concrete and masonry | Concrete and masonry | The entire lineup is built for professional construction and utility tasks, differing only in the required channel width. |
◎ The suitability table below evaluates different usage scenarios and buyer needs to determine which drill modification is best suited for specific jobsite requirements.
| Use Case | Recommended Product | Why |
|---|
| Creating wide utility openings and large boreholes in concrete | Drill Bit AWTools SDS Max 40×400×540 mm (AW43879) | Features the largest diameter in the lineup (40 mm), making it ideal for routing heavy-duty utilities and large anchor installations. |
| Standard construction, anchor installation, and medium-sized through-holes | Drill bit AWTools SDS Max 32 x 400 x 540 mm (AW43864), AWTools SDS MAX 30 x 400 x 540 mm (AW43859), AWTools SDS Max 38 x 400 x 540 mm (AW43874), or SDS Max AWTools 35 x 400 x 540 mm (AW43869) | These intermediate diameters (ranging from 30 to 38 mm) suit most routine construction tasks where the maximum 40 mm size is not required. |
| Preparatory work, smaller anchors, and lower-diameter through-drilling | Drill bit AWTools SDS‑MAX 20 x 400 x 540 mm (AW43829) | The 20 mm diameter places less load on the tool while producing compact holes for smaller fasteners and utility lines. |
The Drill Bit AWTools SDS Max 40×400×540 mm (AW43879) differs from alternatives by offering the largest drilling diameter while maintaining the same overall length and shank type as the rest of the series. It is best suited for professional construction and utility tasks that require creating the widest possible holes in concrete and masonry. Choose this model when project specifications demand a maximum channel width, whereas thinner modifications from the same line are better suited for standard or lighter-duty applications.
