SDS Max drill bit AWTools 40 x 600 x 740 mm for rotary/hilti drills

SDS Max drill bit AWTools 40 x 600 x 740 mm is designed for use with SDS Max compatible rotary and hammer drills to create large-diameter holes in concrete, masonry and similar building materials. With a 40 mm cutting diameter and an overall length suited for through and deep drilling, this bit is intended for professional tasks where reliable penetration and chip removal are required. The carbide-tipped head and robust flute design support sustained drilling in demanding environments while the shank matches SDS Max tool holders for secure coupling.

Advantages

The AWTools SDS Max 40 mm drill bit provides consistent hole quality and efficient debris evacuation thanks to its deep helical flutes. Its carbide cutting tip is engineered for prolonged wear resistance when drilling into reinforced concrete and hard masonry. The SDS Max shank ensures stable transmission of impact energy and reduces slippage in the drill chuck. Overall construction balances rigidity and torsional strength to withstand heavy-duty use.

Suitable for

• Drilling 40 mm diameter holes in concrete and reinforced concrete
• Creating passage holes for anchors, dowels and pipe penetrations
• Heavy renovation and structural modification work
• Installation of HVAC, plumbing and electrical systems requiring through-holes

Key specifications

• Cutting diameter: 40 mm
• Working length: 600 mm
• Overall length: 740 mm
• Shank type: SDS Max compatible
• Tip: carbide-tipped cutting head
• Flute design: deep helical flutes for chip removal
• Material compatibility: concrete, masonry, reinforced concrete

How to use

Install the bit into an SDS Max compatible rotary or rotary-hammer drill, ensuring it locks securely in the tool holder. Select the rotary-hammer or hammer-drill mode appropriate for the material. Begin drilling at low rpm to seat the tip, then apply steady pressure and allow the tool's impact action to advance the bit. Periodically withdraw the bit to clear accumulated dust and debris from the flutes when drilling deep holes. For through-holes, continue until the required depth is reached and then retract the bit carefully.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask or extraction. Match drill speed and impact settings to the material and machine manufacturer guidance. For reinforcement bars, use intermittent extraction and consider a rebar-cutting accessory if frequent rebar contact is expected. Store the bit dry and inspect the tip before use; replace when carbide tip shows significant wear or damage.
