Caulking Gun Cordless for 20V Max Battery – Electric Sealant Gun with 600kg Thrust, 6 Speed, Anti-Drip, LED Light, 300ml Cartridge Kit for Home Sealing & Installation
About this item
- 600kg Thrust & 6-Speed Control – From Window Beading to Large Gaps: This cordless caulk gun delivers a stable 600kg (±50kg) of thrust, easily handling thin sealants or thick construction adhesives. With 6 adjustable speeds (60 200mm/min), you get smooth application for delicate window beading at 60mm/min or rapid gap filling at 200mm/min – complete control over every job.
- Compatible with 20V Max Batteries – Power You Already Own: Works seamlessly with 20V Max series batteries (DCB200, DCB201, DCB203, DCB204, DCB205, DCB206). Batteries sold separately, but if you already have tools from that popular platform, you’re ready to go. Cord free freedom means you can work on a ladder, under a sink, or in a tight crawl space without hunting for a socket.
- Automatic Anti-Drip System – No Messy Strings, No Wasted Sealant: Release the trigger and the plunger rod instantly retracts, stopping any ooze or drip. No more sticky trails or wasted material. Whether you’re sealing a bathroom basin, kitchen worktop, or window frame, you get clean, neat lines – and less time cleaning up afterwards.
- Built-in LED Light – See Clearly in Dark Workspaces: A bright LED work light illuminates those hard to see areas: under the kitchen sink, behind a toilet, inside a cabinet, or in a dark corner. Day or night, you can apply silicone accurately without guessing where the nozzle is going – a real help for evening repairs or poorly lit garages.
- Ergonomic Design & Lightweight Body – Work Longer Without Aching: Compared to a manual caulking gun, this cordless version cuts hand and wrist strain dramatically. The comfort grip handle and balanced body let you seal a whole bathroom or run a full room of skirting boards without your hand cramping halfway through. Good for professionals and DIYers tackling big projects.
- Complete Kit with 300ml Cartridge Compatibility – Open & Go: Comes with a 3 in 1 caulk remover tool, 4 silicone pads, 3 nozzle tips, and a cleaning needle. Works with all standard 300ml (10oz) sealant cartridges – no extra adapters needed. From home DIY to caravan sealing or craft projects, you’ve got everything in one box
Product description
Q1: Can this cordless caulk gun handle both thin sealants and thick adhesives? A1: Yes. It delivers a stable 600kg (±50kg) of thrust and has 6 speeds (60 200mm/min). For delicate window beading, use a slower speed for smooth application; for filling large gaps, turn it up. You get complete control without struggling with manual squeezing. Q2: Which batteries does it work with? A2: It is compatible with 20V Max slide pack batteries (models DCB200, DCB201, DCB203, DCB204, DCB205, DCB206). If you already own tools from that popular platform, you don’t need to buy new batteries. The cord free design lets you work on a ladder, under a sink, or in a tight crawl space without hunting for a socket. Q3: Does it drip or make a mess when I release the trigger? A3: No. The anti drip system retracts the plunger rod instantly when you let go of the trigger. That stops oozing and messy strings, so you get clean, neat lines on bathroom basins, kitchen worktops, or window frames – and spend less time cleaning up. Q4: Can I use it in dark or cramped spaces? A4: Absolutely. The built in LED light shines right where the nozzle points. It illuminates under sink cabinets, behind toilets, dark corners, or any poorly lit area. Day or night, you can apply silicone accurately without guessing – a real help for evening repairs or gloomy garages. Q5: Is it heavy? Will my hand get tired after a big job? A5: Not at all. The lightweight body and ergonomic comfort grip handle dramatically reduce hand and wrist strain compared to a manual caulking gun. You can seal a whole bathroom or run skirting boards around a room without cramping – good for professionals and DIYers tackling large projects. Q6: What else comes in the box? A6: The kit includes a 3 in 1 caulk remover tool, 4 silicone pads, 3 nozzle tips, and a cleaning needle. It works with all standard 300ml (10oz) sealant cartridges – no extra adapters needed. From home DIY to caravan sealing or craft projects, you’ve got everything ready to go.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
