Key Features of Makita 1 3 8 Inch SDS MAX Dust Extraction Bit
Makita 1-3/8" x 24" SDS-MAX Dust Extraction Drill Bit B-63937
The Makita B-63937 1-3/8" x 24" SDS-MAX Dust Extraction Drill Bit is designed for heavy-duty concrete and reinforced-concrete drilling where efficient dust removal and accurate hole preparation are important. Its integrated dust-extraction design allows debris to be drawn out of the hole while drilling, helping combine drilling and hole cleaning into a single operation.
With a 10-cutter solid carbide head, self-centering tungsten carbide tip, and 15-3/4" usable length, this bit is particularly suited to applications such as chemical anchor installation. When connected to an appropriate dust extractor and used with compatible equipment, the system helps reduce airborne silica dust and improve drilling productivity.
Key Features
Integrated dust extraction: Extraction holes remove drilling debris directly from the hole while the bit is operating.
Drilling and hole cleaning in one step: Helps streamline concrete hole preparation, particularly for chemical anchors.
10-cutter solid carbide head: The 6/4/6 design incorporates six front cutters, four side cutters, and six side stabilizers for a total of 10 cutting edges.
Durable carbide construction: The solid carbide head is designed for demanding concrete and reinforced-concrete applications.
Self-centering tungsten carbide tip: Helps the bit stay aligned for more accurate holes.
Improved dust evacuation: Removing debris during drilling can help increase drilling speed and extend bit life.
15-3/4" usable length: Provides substantial drilling depth while maintaining a 24" overall length.
Broad vacuum compatibility: Designed to fit most common dust extractor vacuums.
SDS-MAX shank: Compatible with rotary hammers that accept SDS-MAX bits.
Dust-control solution: Makita identifies the SDS-MAX dust extraction drill bit as an OSHA Table 1 compliant solution when used with approved control devices.
10-Cutter Design
The B-63937 uses Makita's 6/4/6 solid carbide head design. This configuration consists of six front cutters, four side cutters, and six side stabilizers. The resulting 10 cutting edges are engineered to provide durability when drilling concrete and reinforced concrete.
The self-centering carbide tip also helps reduce bit wandering, making it easier to produce accurately positioned holes for anchors and other concrete fastening applications.
Dust Extraction Performance
Unlike a conventional solid drill bit, the B-63937 incorporates dust extraction holes that allow drilling debris to be removed from the hole as the bit cuts. When connected to a suitable dust extractor, this approach reduces the accumulation of debris and helps limit airborne silica dust.
For chemical anchor installation, the integrated extraction system can also eliminate a separate hole-cleaning step in appropriate applications, helping improve workflow efficiency. Dust-control performance depends on using the complete setup with an appropriate approved dust extractor and control device.
Ideal Applications
The Makita B-63937 is suitable for:
Concrete drilling
Reinforced-concrete drilling
Chemical anchor installation
Concrete fastening preparation
Construction and remodeling
Commercial building projects
General masonry drilling
Applications where integrated dust extraction is desired

Compatibility
The B-63937 is intended for use with rotary hammers that accept SDS-MAX shank bits. It is also designed to connect with common dust extractor vacuum systems. The dust extractor and rotary hammer are separate equipment and are not included with the drill bit.
What's Included
1 × Makita B-63937 1-3/8" x 24" SDS-MAX Dust Extraction Drill Bit
The bit is supplied as a single unit. Makita also lists B-63943 as a replacement vacuum attachment for its SDS-MAX dust extraction drill-bit system.
Why Choose the Makita B-63937?
The Makita B-63937 combines large-diameter concrete drilling with integrated debris extraction, making it a practical choice when clean, accurately prepared holes are required. Its 10-cutter carbide head provides durability for demanding concrete and reinforced-concrete work, while the hollow dust-extraction design helps remove debris during drilling rather than leaving the hole to be cleaned separately.
For contractors and construction professionals performing chemical anchor installation, concrete fastening, and heavy-duty masonry drilling, this 1-3/8" SDS-MAX bit offers a combination of cutting performance, hole accuracy, and integrated dust-management capability.
