#Sds max carbide drill bits plus

If it is a breaking job a SDS-Max rotohammer with a bull point or chisel bit might work – or you might need to move up to an electric jackhammer. When that won’t do there are various core drilling tools. Moving up in hole size – you may need an SDS-Max or Spline Drive rotohammer. A step up would be a hammer drill – but it is still not up to heavier tasks (more or larger holes in harder materials) where a SDS-Plus rotohammer will be more efficient. A conventional drill and masonry drill bit will also work for a few small holes in things like cement block, brick or green concrete. A star drill and a hammer still works – but is way more tedious than using a powered approach. Depending on the size and depth of the holes, hardness of the material, and number of holes required you may select different approaches. If your job requirements need SDS max weight/power then by all means buy or rent SDS max tools, but they’re not something everyone can justify the cost of.Īnchoring things or breaking up stone, brickwork and masonry often requires drilling holes. They are also bigger and bulkier which makes them disadvantageous for working in tight spots or horizontally.

I totally agree the SDS Max class tools greatly outperform SDS plus for many jobs. The hammering action is also very hard on drill chucks so I’d rather not compromise the longevity or precision of my chuck by subjecting it to hammering, even occasional.

Since I very rarely drill in masonry but I use my cordless drill often, I would much rather have the shorter, lighter, non-hammer version. That is the main reason why I have an SDS plus rotohammer.Īlso, having a rotohammer separate from your main drill allows you to pick a non-hammer model instead, which is lighter and more compact. The SDS also has another advantage: they can usually operate in hammer-only mode so you can use them with chisels, scrapers, etc. I think a hammer drill is probably fine for the average DIYer though I could see a contractor picking the rotohammer instead.

The drilling depth is 6” to 7” less than the overall length, and is measured as flute length of the shank of the SDS-Max concrete bit.If you need to drill a lot of small holes in masonry an SDS plus rotary hammer will outperform a “hammer drill”, though that may or may not matter to you.

The designated length of the SDS-Max concrete bit is an overall length measured from end to end.

Ranging in diameters from 3/8” to 2” and in lengths from 13” to 36”, there is a SDS-Max concrete bit available to meet a wide range of drilling requirements.

Special fluting of the SDS-Max concrete bit provides for increased dust removal, which permits faster drill speed.

The grooves allow for a more powerful hammering and rotation motion, which results in faster drilling speed and efficient dust removal.

The SDS-Max concrete bits have groove cut into the shank that allows the bit to move in the chuck to provide extra strength for rotation.

The shank of the SDS-Max concrete bit is approximately 3/4” in diameter, which is much larger than the smaller SDS bits that are approximately 3/8” in diameter.

Many of the large Hilti combo hammer drills utilize the SDS-Max style for the shanks of their drill bits.

The SDS-Max concrete bit is designed specifically for larger hammer drills that use the quick disconnect chuck that accepts the SDS-Max style shank.

The longer SDS-Max concrete bits are used to drill through holes for running electrical conduit or other type of pipes.

The shorter bits, such as the 3/8” x 13” SDS-Max concrete bit, are primarily used to drill holes for the installation of concrete fasteners.

The SDS-Max concrete bit has a carbide tip and is used for drilling holes in concrete.
