SDS MAX Drill Bits
SDS Max drill bits are engineered for large-diameter and deep drilling into reinforced concrete, block and dense masonry. Designed for SDS Max rotary hammers and breakers, these bits deliver maximum impact for structural work.
What Are SDS Max Drill Bits Used For?
Ideal for structural and commercial drilling jobs:
- Concrete Anchors – Drill large holes for resin studs and deep bolt fixings
- Through-Hole Drilling – Penetrate walls, slabs and deep cores for cable or pipe access
- Infrastructure Fixings – SDS Max drill bits used in install of heavy steels, frames and supports
- Utility Cut-Through – Power through cavity walls and dense concrete for services
Used By:
- Structural installers, civil engineers and M&E contractors
- Demolition and groundwork crews
- Any trade using SDS Max hammer drills on site
Choosing the Right SDS Max Drill Bit
Tip spec, length and shank must all match job and tool:
1. Bit Diameter
SDS Max drill bits start around 12mm and go up to 55mm+. Choose based on anchor, conduit or rebar clearance.
2. Cutting Head
4-cutter or X-head tips ensure clean cutting even through rebar — look for carbide inserts and multi-flute debris channels.
3. Length
SDS Max bits range from 300mm to over 1000mm — ensure your drill can handle the torque and support the bit safely.

SDS Max Drill Bit FAQs
Can I use SDS Max bits in an SDS Plus drill?
No — SDS Max shanks are larger (18mm) and won’t fit SDS Plus chucks. They require higher torque and impact force.
What’s the longest SDS Max drill bit?
They’re available up to 1200mm — ideal for deep slab penetrations or large conduit runs. Use with SDS Max drills rated for long reach.
Can SDS Max bits cut through rebar?
Yes — if they’re fitted with carbide 4-cutter or X-head tips. Always drill steadily and allow cooling if hitting dense reinforcement.
What’s the difference between SDS Max and core bits?
SDS Max drill bits are solid — used for boring. Core bits are hollow and cut around the edge — better for creating voids in block and brick.
