"I used them and they are fantastic. An electricians dream."

"Hard to find these generally in wholesalers and tools shops. Can be ordered but only if you know there available in the first place. Until last week I'd not seen this saw. One of my workmates has the 20 and 25mm saws he'd picked up from Edmundsons at one of the London airports whilst working there. I used them and they are fantastic. An electricians dream. So much so that I've ordered the 'Gang of Three' - 20 25 and the 32mm. Around £43 with postage. Asked said workmate how long he'd had and been using his and at 3 years and counting, that's got to be great value. All I can add is 'Get along Postie'!"

"They'll cut a neater cleaner hole, and quicker too - Worth the money."

"Far and away better than general service hole saws us trade people usually buy. These are 21st century gear. Used with care they'll cut a neater cleaner hole, and quicker too! Recommend cutting oil as this will extend the life by miles. Worth the money."

"Five Stars"

"Best holesaw for cutting tray,trunking and panels just don't cut galvanised boxes."

"Good if not better than the red ones."

By mike windsor on 12 February 2017

"nice product, good if not better than the red ones. ideal for drilling sheet steel, trunking etc as they dont fly through the hole once drilled due the the shank on the body."

"Just the job"

"Arrived as stated without hassle. We wanted the saw primarily to cut drain holes in the stern of a boat so it had to tackle fairly thick fibreglass and chipboard. Managed everything and, unlike some cheaper holesaws, it still has plenty of life left. Not the cheapest but worth the money."
