Drill Bit AWTools SDS‑MAX 28 x 600 x 740 mm

AWTools SDS‑MAX 28 x 600 x 740 mm is a long-reach drill bit designed for use with SDS‑MAX rotary hammers. With a 28 mm cutting diameter and extended length, this solid bit enables drilling through concrete, masonry and natural stone where deep or through-holes are required. The geometry and shank fit are matched to SDS‑MAX systems for secure retention and efficient transfer of impact energy.

Advantages

This SDS‑MAX drill bit provides stable drilling performance over long depths thanks to its optimized flute design and robust hard tip suitable for percussion drilling in dense materials. The 28 mm diameter balances hole size and structural strength, while the extended overall length allows access to recessed or hard-to-reach locations without the need for extensions. The standard SDS‑MAX shank ensures reliable locking and easy removal from compatible chucks.

Suitable for

• Drilling through reinforced and non-reinforced concrete
• Creating deep holes in masonry and natural stone
• Installing long anchors, through-rods and conduit runs
• Professional construction and renovation tasks requiring extended reach
• DIY projects that need deep or through holes with SDS‑MAX rotary hammers

Key specifications

• Cutting diameter: 28 mm
• Working length: 600 mm
• Overall length: 740 mm
• Shank type: SDS‑MAX compatible
• Intended materials: concrete, masonry, stone

How to use

Mount the bit into the SDS‑MAX rotary hammer according to the tool manufacturer’s instructions until it locks securely. Select an appropriate hammer or rotary‑percussion mode and use steady axial pressure, allowing the tool to perform the impact work rather than forcing the bit. For through‑holes, periodically withdraw the bit to clear dust and debris and reduce heat buildup. Use appropriate personal protective equipment including eye protection, hearing protection and dust extraction or masking when drilling in occupied spaces.

Usage recommendations

For prolonged bit life when drilling highly abrasive or reinforced concrete, use intermittent operation with dust removal and moderate cooling pauses. Ensure the rotary hammer has sufficient impact energy rating for a 28 mm SDS‑MAX bit, and choose drill speeds and feed rates recommended by the tool manufacturer.
