24-33 | SDS MAX Rotary hammer showdown | GRH05 / HR005 vs GBH18v-45c vs DH36DMAQ2M
In this episode, we take a look at some of the SDS max rotary hammer drills. These are cordless hammer drills designed to deliver the performance of a corded SDS Max wood Hammer Drill. Previously these tools were tested using SDS plus size bits to drill half inch holes but in this episode, we put the show down to test drilling one inch holes, which are better suited for this class of tool. The question is, can these tools deliver on the performance? Let's find out.
-------------------------------------------------------------------
GRH05 / HR005
OUTPOWER: Makita-built brushless motor along with 40V Max XGT battery combine to deliver the power performance required for heavy-load application
OUTSMART: Auto-start Wireless System (AWS) utilizes Bluetooth technology for wireless power-on/off communication between tool and dust extractor (AWS Transmitter sold separately)
OUTLAST: Extreme Protection Technology (XPT) is engineered for improved dust and water resistance for operation in harsh conditions
Anti-Vibration Technology (AVT) is an internal counterbalance system along with vibration-absorbing handles that work together to reduce vibration
Active Feedback-Sensing Technology (AFT) electronically turns off the motor if rotation of bit is suddenly forced to stop
Electric brake allows the tool to be repositioned faster for maximum productivity
Constant speed control automatically applies additional power under load for optimum performance
Soft start suppresses start-up reaction for more precision and better accuracy
Soft no-load function automatically reduces the speed of the motor when idling to help increase tool life and performance
Built-in L.E.D. light with an independent on/off switch illuminates the work area
Variable speed dial enables the operator to match the speed to the application
2-mode operation for Hammering with Rotation or Hammering Only for increased versatility
Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears during a bind-up situation
The digital communication within XGT actively monitors and protects against overload, over-discharge and overheating

BOSCH GBH18V-45CK
PROFACTOR performance – delivers corded hammer performance for an 18V SDS-max 1-7/8 In. rotary hammer
Superior impact – delivers 9.3 Ft.-Lbs. of impact energy (EPTA) for maximum performance when drilling and chiseling
Lightweight, at only 17.6 Lbs. – provides maneuverability for concrete drilling anywhere
BITURBO Brushless Technology – featuring a brushless high-performance motor and drive-train system engineered to take full advantage of the additional power generated by CORE18V High Power batteries
KickBack Control technology – reduces the risk of sudden tool reactions in binding conditions
Anti-vibration system – helps reduce vibration with a longer air cushion in the hammer tube, dampeners in the handle and a counter-balance weight in the hammer mechanism
Robust power system – produces 0-2,760 no-load bpm and 0-305 no-load rpm
Vario-Lock positioning – rotates and locks chisel to optimize working angle
Soft Start and controlled rpm – adjusts rpm and bpm for controlled drilling and chiseling applications in softer materials such as brick or tile
-------------------------------------------------------------------
DH36DMAQ2M
POWER: 4-Stage speed selection from 260-590 RPM and 1,420- 2,860 BPM with 7.7 ft-lbs of impact energy for busting through hard material
MODES: Switch between hammer and hammer drill for flexibility within a range of applications
LOW VIBRATION: Low vibration handle (LVH) with soft grip ensures a high vibration absorbing effect for added user comfort
REACTIVE FORCE CONTROL: Senses the tool overload and stops rotation to ensure user safety and protect the tool motor and battery
EASY BIT CHANGE: Quick release bit system for fast and simple bit replacements for different applications
SIDE HANDLE: 360 Degree side handle that provides additional comfort and control
MULTIVOLT: Tool can be powered by multi-volt battery or AC adapter
