24mm Drill Bits

When your project demands deep, large-diameter holes, our professional range of 24mm drill bits delivers the heavy-duty performance you need. Built to handle intense torque and resist wear, these robust bits drive smoothly through tough structural materials without wandering. Whether you are sinking large anchor bolts into masonry, boring clearance holes for plumbing pipes through thick timber, or fabricating metalwork, keeping a dedicated 24mm bit in your kit ensures you can tackle demanding installations accurately and efficiently.

We offer a selection of heavy-duty 24mm profiles designed for specific materials and power tools. Choose from high-performance SDS plus and SDS max masonry bits engineered to power through dense concrete and blockwork with minimal vibration. For fast and clean timber clearance, our 24mm range includes extreme flat wood and auger bits. If you are working with metal, we supply reliable reduced-shank HSS blacksmith bits that fit standard drill chucks. Ensure top-tier results with stock from trusted brands like Bosch, Milwaukee, DeWalt, and Toolpak.

Frequently Asked Questions | FAQs

What is a 24mm Blacksmith drill bit?

A 24mm Blacksmith drill bit (also known as a reduced-shank bit) is a high-speed steel (HSS) bit with a large 24mm cutting head and a narrower base (usually 10mm or 13mm). This stepped-down shank allows you to drill large 24mm holes into heavy-duty metals using a standard drill chuck, eliminating the need for a specialized, large-capacity power tool.

What is a 24mm SDS Max drill bit used for?

A 24mm SDS Max drill bit is designed for heavy-duty rotary hammers and features a thicker, more robust shank than standard SDS Plus bits. This extra strength allows it to withstand extreme hammer action, making it perfect for drilling deep 24mm holes into dense concrete, reinforced masonry, and blockwork for large structural anchors.

Can I use a 24mm flat wood bit in a standard combi drill?

Yes, you can use a 24mm flat wood bit (or spade bit) in a standard combi drill or drill driver, provided it has a standard 3-jaw chuck (most go up to 13mm) and the bit has a compatible hex shank. However, drilling a hole this large requires significant torque, so ensure your drill is powerful enough and use a slower speed setting to prevent the bit from binding or stalling the motor.
