Makita 40V Max XGT AVT Rotary Hammer Kit SDS-PLUS Chuck
Makita 40V max XGT Brushless Cordless 1-3/16 in. SDS-PLUS AVT Rotary Hammer Kit with Interchangeable Chuck
Product Overview
The Makita GRH09M1 is a high-performance cordless rotary hammer designed for demanding concrete drilling applications. Powered by Makita's 40V max XGT Lithium-Ion battery platform, it combines a brushless motor with Anti-Vibration Technology (AVT) to provide strong drilling performance while helping reduce vibration transmitted to the operator.
One of its standout features is the quick-change chuck system, which allows users to switch between SDS-PLUS bits and a 1/2-inch keyless chuck for straight-shank bits. This gives the tool greater versatility than a rotary hammer limited to SDS-PLUS accessories. The kit includes a 40V max XGT 4.0Ah battery, charger, side handle, grease, towel, and tool case.
Key Features
- 40V max XGT cordless power: Delivers the power and runtime needed for heavy-duty concrete applications.
- 1-3/16-inch concrete capacity: Designed for drilling large holes in concrete.
- SDS-PLUS system: Accepts SDS-PLUS rotary hammer bits for efficient concrete drilling.
- Interchangeable chuck: Quick-change system switches between SDS-PLUS and a 1/2-inch keyless chuck for straight-shank bits.
- Brushless motor: Provides efficient power delivery and reduced maintenance.
- AVT Anti-Vibration Technology: Uses a counterbalance system and vibration-absorbing components to reduce vibration.
- Variable-speed operation: Electronic speed control allows the operator to match tool performance to the application.
- 3.9 J impact energy: Provides substantial impact force for demanding concrete drilling.
- Up to 4,500 BPM: High impact frequency supports efficient material removal.
- AWS capable: Can connect wirelessly to compatible dust extractors using Makita's Auto-Start Wireless System transmitter.
- Dust-management capability: Supports compatible dust-extraction solutions for concrete drilling.
- Compact cordless design: Provides freedom of movement without an extension cord.
- Complete kit: Includes a 4.0Ah battery and charger.

Specifications are based on Makita's published GRH09M1 specifications.
40V max XGT Brushless Performance
The GRH09M1 pairs a Makita-built brushless motor with a 40V max XGT battery to deliver the output required for heavy-load concrete drilling. Its maximum drilling capacity in concrete is 1-3/16 inches, with an optimum drilling range of 3/16 to 3/4 inch.
The variable-speed trigger and dial allow the operator to adjust the tool's speed according to the material, bit size, and drilling task. The hammer produces up to 4,500 blows per minute and operates at up to 840 RPM with no load.
Interchangeable Chuck System
The quick-change chuck is a major advantage of this model. The tool can be configured for SDS-PLUS bits for rotary hammer applications or switched to the supplied 1/2-inch keyless chuck when straight-shank drill bits are preferred.
This makes the GRH09M1 more versatile than a rotary hammer that accepts only one type of bit. Users can change chuck configurations according to the material and drilling method without changing to a completely different tool.
AVT Anti-Vibration Technology
Makita's AVT (Anti-Vibration Technology) is designed to reduce vibration transmitted to the operator. The system uses a counterbalance mechanism together with vibration-absorbing handles and housing components.
This is particularly valuable during extended concrete drilling, where continuous vibration can contribute to operator fatigue.
Concrete Drilling Capability
With 3.9 J of impact energy, the GRH09M1 is designed for demanding drilling work in concrete. Its maximum standard drilling capacity is 1-3/16 inches, while Makita specifies a maximum 3-1/8-inch capacity when using a core bit.
The tool can therefore handle applications ranging from smaller anchor holes to larger openings where compatible core-drilling accessories are appropriate.
AWS Wireless Connectivity
The rotary hammer is Auto-Start Wireless System (AWS) capable. When paired with a compatible AWS transmitter and dust extractor, the system can provide wireless communication between the tool and extractor.
This helps simplify dust-management setups by allowing the extractor to start and stop in response to tool operation. The AWS transmitter is sold separately.
Dust Management
Concrete drilling can produce significant amounts of fine dust. The GRH09M1 supports compatible dust-extraction solutions, including Makita's OSHA-compliant HEPA dust-extraction options.
Using appropriate dust collection can help improve jobsite cleanliness and reduce airborne dust during drilling operations.
Battery and Runtime
The kit includes one 40V max XGT 4.0Ah Lithium-Ion battery. Makita states that the tool can produce up to 135 holes of 3/8-inch diameter per charge under its specified test conditions. Actual runtime will vary depending on bit diameter, material hardness, drilling depth, operator technique, and other jobsite conditions.
