BOSCH HC2068 3/8 in. x 22 in. x 24 in. Bulldog SDS-Plus Rotary Hammer Bit
The Bosch HC2068 is a 3/8 inch SDS-Plus bit with a 24-inch length designed for long-reaching holes in masonry. Its two-cutter head reduces resistance and speeds drilling, while a centering tip helps place anchors precisely. An integrated wear mark indicates when the bit is worn, aiding planning for replacements during extended work. This bit is well-suited for overhead or deep-wall installations where a long reach is essential and consistent performance matters in concrete, brick, and stone.
SALI SDS Plus Rotary Hammer Drill Bit 5/8″ x 24″
The SALI 5/8″ x 24″ SDS-Plus bit is supplied as a 1.2-pack designed for drilling through concrete, brick, and cement walls. Carbide tips provide durability in hard materials, making it suitable for heavy-duty tasks. The SDS-Plus shaft ensures compatibility with a range of rotary hammer drills, though it will not fit standard chucks. This long bit delivers high cutting performance for long holes and anchors in tough substrates.
Drill America 1/4″ X 24″ PRO SDS-Plus Hammer Bit
Drill America’s 1/4″ x 24″ PRO SDS-Plus bit combines a dual carbide cutter head with an optimized cutting edge and recessed tip for extended life and strong performance in concrete and reinforced steel. The 3D helix design clears dust quickly, reducing blowback and maintaining easier drilling. Its design supports longer reach while maintaining drill steadiness under load, making it a reliable choice for installers and professionals handling long hole drilling.
Bosch HCFC5013 1/2 in. x 24 in. x 29 in. SDS-Max SpeedXtreme
The Bosch HCFC5013 is a 1/2 inch SDS-Max drill bit with a 29-inch length and a carbide head. Its four-cutter design delivers enhanced life in reinforced concrete and hard aggregate, aided by diffusion-bonding technology that claims up to five times longer life than competitors. The four-cutter head ensures wide cutting diameter and steady power transfer for challenging drilling tasks, including hitting through rebar with fewer stalls and jams.
FROOOK SDS Plus Rotary Hammer Drill Bit, 1-1/2″ x 24″
FROOOK’s SDS-Plus bit features four carbide cutting edges and a coated head for enhanced durability and faster drilling. The 1-1/2 inch diameter plus 24 inch length makes it capable of penetrating through dense masonry, concrete, and natural stone. An optimized double-spiral flute geometry promotes chip removal and reduces wobble, helping prevent bit binding and ensuring stable operation in long, demanding holes.
Bosch HC4C2068-3/8 in. x 22 in. x 24 in. SDS-Plus Bulldog Tough
The Bosch HC4C2068 features a four-cutter carbide-tipped head designed to extend life in concrete with rebar. The head’s four cutting edges improve efficiency when penetrating tough materials, while a centering tip aids precise anchor hole placement. This design helps reduce the risk of the bit getting stuck and supports consistent drilling performance across varied masonry scenarios.
1-1/2 in. X 24 in. Masonry Drill Bit, SDS Max
KATEYA offers a carbide-tipped 1.5″ x 24″ SDS-Max masonry bit with a cross-tip W flute design and four cutting points. While optimized for SDS-Max hammer drills, the bit’s robust carbide construction and geometry are intended to deliver efficient material removal in dense masonry and concrete. It suits professional applications requiring long reach in large-diameter holes.
Torxero 2 in X 24 in SDS MAX Bit
Torxero’s 2″ x 24″ SDS-Max bit is sized for heavy-duty drilling in masonry, concrete, stone, and brick. The carbide-tipped head provides rigidity and long wear life, while the SDS-Max shank ensures compatibility with high-torque hammer drills. The long length enables drilling deep anchors and large-diameter holes with sustained power transfer in tough substrates.
Buying Guide
- Drill type compatibility: Ensure the bit matches your drill’s shank system (SDS-Plus vs SDS-Max) and that your tool supports long 24-inch lengths without interference.
- Carbide head versus steel: Carbide-tipped heads last longer in hard materials such as reinforced concrete, brick, and stone, but may come at a higher cost.
- Cutter design: Four-cutter heads tend to deliver longer life and more stable drilling, especially in dense substrates, while two-cutter designs may offer faster cutting in some softer concretes.
- Length versus rigidity: Longer bits improve reach but can increase wobble. Look for bits with reinforced flute geometry and dust-reduction features to maintain accuracy.
- Dust management and wear indicators: Bits with integrated wear marks or dust-collection features help manage maintenance and reduce downtime on professional sites.
- Application scope: For rebar-heavy concrete, prioritize bits with reinforced cutting edges and center tips for precise anchor placement and reduced jamming.
- Budget and durability: In large projects, investing in longer-lasting carbide-tipped bits can reduce replacement frequency and improve overall productivity.
