Drill Bit AWTools SDS‑MAX 16 mm x 600/740 mm, AWTools AW43820

SDS‑MAX drill bit AWTools AW43820, 16 mm diameter with a 600 mm working length and 740 mm overall length, is designed for use with SDS‑MAX rotary hammers to drill deep holes in concrete, masonry and similar hard materials. The bit’s dimensions allow accurate, extended-reach drilling while maintaining compatibility with professional SDS‑MAX tool chucks. The solid construction and geometry are intended to provide efficient material removal and stable drilling performance under load.

Advantages

The AWTools SDS‑MAX 16 mm x 600/740 mm drill bit offers a balance of depth and rigidity for extended drilling tasks. Its long working length reduces the need for extensions when creating deep anchor or conduit holes. The bit’s shank and flute design support consistent chip evacuation and reduce binding during rotary hammer operation. Manufactured for compatibility with SDS‑MAX systems, it enables reliable engagement and power transfer between the tool and bit.

Suitable for

• Drilling deep anchor holes in concrete and reinforced concrete
• Creating passages for conduits and plumbing in masonry walls
• Installing dowels, rebar sleeves or long fasteners in structural elements
• Professional construction and renovation applications requiring extended-reach holes
• DIY projects where precise long holes are needed in hard substrates

Key specifications

• Diameter: 16 mm
• Working length: 600 mm
• Overall length: 740 mm
• Shank type: SDS‑MAX compatible
• Intended materials: concrete, masonry and similar hard substrates
• Application: rotary hammer drilling with hammer and rotation action

How to use

Fit the drill bit into a compatible SDS‑MAX rotary hammer according to the tool manufacturer’s instructions, ensuring the bit is fully seated and locked. Select the hammer-drill mode (rotation with hammering) and start drilling at low speed to establish the hole, then increase power as needed while maintaining a steady, straight feed. Apply controlled pressure — let the tool’s hammer action do the work rather than forcing the bit. Periodically withdraw the bit to clear debris and improve cooling; for very deep holes, withdraw more frequently to evacuate dust.

Usage recommendations

Use appropriate personal protective equipment, including eye and ear protection, dust mask and gloves. For reinforced concrete, check for reinforcement location before drilling. Match drill speed and feed to the material hardness, and avoid excessive lateral forces to prevent bit damage. Store the bit in a dry place to protect the cutting edges and shank.
