Product Information
Full details
This DeWalt twin pack, featuring the DCH273 XR SDS Brushless Rotary Hammer Drill and DCG405N-XJ Angle Grinder with two Powerstack 5.0AH batteries, is designed for professional tradespeople tackling demanding construction and renovation tasks. Its key benefit lies in the high-speed drilling performance and extended runtime, allowing for more work to be completed per charge. A potential caveat is the specialized nature of the SDS chuck, which requires compatible drill bits.

FAQs
What type of drill bits does the DCH273 use?
The DeWalt DCH273 Rotary Hammer Drill uses SDS Plus bits. Standard round shank drill bits are not compatible.
Are the Powerstack batteries compatible with older DeWalt 18V tools?
Yes, the DeWalt Powerstack 5.0AH batteries are fully backwards compatible with all DeWalt XR 18v tools.
Can I use the DCH273 for normal drilling in wood or metal?
Yes, the DCH273 features an 'impact stop' mode which disables the hammering action, allowing for rotary-only drilling in wood and metal.
What is the maximum disc size for the DCG405 grinder?
The DeWalt DCG405N-XJ Angle Grinder has a disc diameter of 125mm.
How do I maintain the SDS chuck on the rotary hammer?
It is recommended to periodically lubricate the SDS chuck with a small amount of specialized SDS grease to ensure smooth operation and prolong its lifespan. Keep it free from debris.
Does this kit include batteries and a charger?
The DeWalt DCH273H2T-GB twin pack includes two DeWalt Powerstack 5.0AH batteries. The DCG405N-XJ angle grinder is typically sold as a bare unit (tool only), so a charger and batteries may need to be purchased separately if not already owned, though this specific bundle includes batteries for the drill.
What is the benefit of brushless motors?
Brushless motors offer increased efficiency, longer tool life, better power output, and reduced maintenance compared to brushed motors.
Troubleshooting
Rotary hammer not drilling effectively
Ensure an SDS bit is correctly inserted and locked in the chuck. Check if the correct mode (hammer drilling) is selected. Verify the bit is sharp and suitable for the material. Check battery charge level.
Angle grinder stops unexpectedly
Check the battery charge level. Ensure the tool is not overheating; allow it to cool down. Check for any obstructions in the air vents or disc area. Ensure the disc is correctly installed and not binding.
Tool not powering on
Confirm the battery is fully charged and properly seated in the tool. Check the battery contacts for dirt or damage. Try a different Powerstack battery if available.
Excessive vibration during use
Ensure the correct bit or disc is installed securely. Check for wear on the SDS chuck or grinder flange. Ensure you are using the appropriate accessory for the task.
Reduced runtime from batteries
Ensure batteries are stored correctly and not exposed to extreme temperatures. Clean battery terminals. If the issue persists, the battery may need replacement.
