BoschProfessional 2608587010 13-Piece Self Cut Speed Spade Bit Set with 1/4 Inch Hex Shank, 10mm-32mm

For the job they are advertised to do, these are spot on. Just make sure you know what you want them to do. If you use a hand power drill and want to go through wood, these are for you. If you want to drill a hole partway through wood, well that ain’t happening. They take over when the worm bites the wood and there’s no stopping them! I foolishly put one in my drill press and nearly went through the table. If I hadn’t turned the machine off the bit would be in China by now! As said, if you’re buying these to go through rafters for example, they’re a great product.

Great set of flat bits and the cheapest way to get yourself set up. Theses speed bits are great pulling through wooden joists with ease. Just remember if you hit a nail they are going to last very long so check before you drill. FYI if you are after a flat bit that can deal with hitting nail and powering through then you need the Bosch nail strike flat bits which are awesome. Unfortunately you will have to get these from America as they aren’t available in the UK

Received the Bosch bits in a sealed plastic package. The actual case was filthy has oil marks and finger prints all over it.I have run my finger over the the edges and the paint is crumbling off. If I didn’t need them for a job I would return them straight away. Can’t say much of longevity as not used them yet.

First off,all my tools are bosch blue. Love em. Proper work horses. But who the hell make these? Came to use em to go through some 3 x 2. After about 6 holes size 14 gone Blunt and I mean proper blunt. Sending back for a refund.

These have such a bite on them that you have to be on your guard. They cut through wood at an amazing rate.Can't fault them but the bigger bits need you to be aware that there is a big bite as the screw point pulls the spade through the wood at pace. Still if you cut lots of holes [plumbing & electrics] these are a must.

These drill into wood quickly and easily. Really easily! They don't make the neatest holes but they do a decent job and I find myself using them often. A good set with good selection of sizes.

With the worn on the end they are so fast at boring holes not like the standard flat bits when you need to push them though the timber with some force.

Good quality cuts really well be careful when you use them to fit a mortise lock they keep on going into the door
