The Sutton Tools 20 x 400mm DB TCT masonry drill bit drills large-diameter holes in stone, brickwork and concrete. Its tungsten carbide tip stands up to abrasive surfaces, and the long 400mm length reaches deep into solid masonry for anchors, conduit and heavy fixings.
A double spiral flute pulls dust out of the hole to keep cutting smooth and reduce heat, while the brazed carbide percussion tip is made for rotary hammer and percussion drilling. Well suited to tradespeople and serious DIYers working with masonry walls and concrete slabs.

Great value for money
Spent a while looking for the right Sutton Tools and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.

Outstanding value
Bought this on a bit of an impulse after seeing it on the site and really glad I did. Quality is much better than the price suggests — feels premium and well made. Ordered Monday and it arrived Wednesday in Sydney. Nothing loose or damaged. A few people have asked where I got it.
Good buy — fast shipping
Really good value — compared it to similar products at twice the price and there is very little difference in quality. Fast shipping and arrived in perfect condition.
