The Kamco RadHammer (MI040) is an SDS drill-attachable radiator vibrator designed to loosen stubborn corrosion and sludge deposits during power flushing. Over time, debris accumulates inside radiators and creates cold spots that can become solid and resistant to a chemical flush alone. The RadHammer fits into a standard SDS chuck and, in hammer-only (non-rotational) mode, applies moderate-pressure, high-frequency vibration directly to the radiator surface to break these deposits free so they can be carried away by the power flush.
It is fitted with a replaceable flat-faced head, so wear from repeated impact use does not mean replacing the whole tool.

Safety & Usage Warning
Always refer to the SDS drill manufacturer's safety instructions before use, and wear ear defenders. Never use the RadHammer on any radiator connected to anything other than standard copper pipework. Vibrating and removing stubborn deposits may uncover hidden corrosion already present in the heating system, which can lead to leaks. Loose paint may be damaged or removed during use — always indemnify yourself against any damage the use of the product may cause.
Use With Care
Do not apply excessive force — the more pressure applied via the SDS drill, the more powerful the vibrational force on the radiator, increasing the risk of paint damage. The RadHammer is not intended for continuous use or for working the whole radiator surface; excessive use can damage the radiator or the RadHammer head itself. Head life is considerably reduced if applied to a radiator at an angle rather than perpendicular.
SDS Drill Compatible
Designed to fit directly into a standard SDS chuck, allowing installers to use their existing power flushing drill setup without dedicated equipment.
Targeted Deposit Removal
Applies high-frequency vibration at the exact location of a cold spot, speeding up the chemical flushing process and improving overall cleansing efficiency on stubborn, older systems.
Replaceable Flat-Faced Head
The impact head (MI040B) wears with repeated use and can be replaced independently, extending the working life of the tool.
Works With Infra-Red Diagnosis
Pairs naturally with an infra-red thermometer survey — installers can map cold spots on each radiator before the flush, then target the RadHammer precisely at those locations.
Non-Rotational Hammer Action
Used exclusively in a drill's "hammer only" (non-rotational) mode, delivering direct impact vibration rather than a drilling action against the radiator surface.
Full-Flow Compatibility
Intended for use on an individual radiator receiving full flow from the Clearflow (or equivalent) power flushing pump, ensuring loosened debris is carried away rather than redeposited.

How to Use the RadHammer
- Monitor each radiator for cold spots and note their locations — an infra-red thermometer is ideal for this.
- During the power flush, re-check these locations to identify any stubborn areas where deposits still remain.
- Attach the RadHammer to an SDS drill and set the drill to "hammer only" mode (non-rotational).
- Clean any debris or dirt from the face of the RadHammer and the surface of the radiator.
- Hold the drill so the RadHammer face is perpendicular to the radiator surface at the problem area, and run the drill for approximately 3 seconds while applying moderate pressure.
- Check the radiator temperature and repeat at other stubborn areas if required.
Frequently Asked Questions
What tool does the RadHammer attach to?
It is designed to fit into a standard SDS chuck, so it can be used with the same SDS drill an installer already carries for other work.
What drill setting should be used?
Set the drill to "hammer only" (non-rotational) mode — the RadHammer is an impact tool, not a rotary drilling attachment.
Can it be used on any radiator?
No. Never use the RadHammer on a radiator connected to anything other than standard copper pipework, as vibration could damage other pipe materials or fittings.
What happens when the head wears out?
The flat-faced impact head is replaceable — order part number MI040B from Kamco rather than replacing the whole tool.
Is there a risk of damage during use?
Yes — used incorrectly, the RadHammer can damage radiator paintwork or uncover pre-existing hidden corrosion, potentially leading to leaks. Always apply moderate pressure only, hold the head perpendicular to the radiator, and avoid continuous or whole-surface use.
Do I need ear protection?
Yes. Kamco recommends wearing ear defenders when operating the RadHammer, and to always follow the SDS drill manufacturer's safety instructions.
