This guide reviews how to drill into concrete safely and effectively. Follow these steps to tackle your next project like a pro.

For this project, you’ll use a hammer drill. A hammer drill combines the rotary motion of a standard drill with a mechanized hammering motion. This combination makes it possible for a hammer drill to pass through hard materials like concrete.

Hi Chris, 30° from the horizontal. Even for folks that have bought their toolholders I'd reccomend making the grinding jig. It's much nicer to use than the supplied one.

Mine never was used much in anger, (reverted to replaceable tips) but a few months ago, made a bigger version to take 5/16 toolbits.

Agree wholeheartedly with previous replies – I splashed out and bought both LH & RH versions plus the parting off tool …… and apart from using a round shaping tool and boring bars they have been in permanent use since unpacked over 12 months ago. A really excellent tool choice and the expense side of things soon fades as you get to appreciate just how good they are.

Having just looked at the Wimberley holder manual the tool grinding procedure seems to be as intricate as for a regular cutting tool whereas the Diamond Tangential tool grinding procedure (AND alignment in the tool holder) is just so straightforward, achievable by anyone of any level of expertise, and more importantly – consistent.

The Wimberley tool looks quite interesting but at a rather expensive $85 shipping to the UK plus the tool cost of $59 I'll wait or make one.

Hi Nick, Yes they are good, but as I'm too tight to buy at the prices they want I made my own. It's not hard to make one if you have a mill. Keith.

I've also made a height gauge specific for my Lathe as well so set up is very quick. Probably quicker than using a QCTP.

If the threads of a screw won't grip, you can try to drill a new hole and relocate the screw. If this is not possible, use an anchor.

One point is that the supplied sharpening jig leaves your fingers VERY close to the grindstone wheel, so I have manufactured a longer version. I also had to fit a spacer onto the grinder tool rest to bring the base of the tool sharpener in-line with the wheel centre line.

Before drilling, determine the drill bits you’ll need for the project. If you’re using concrete screws, the correct size drill bit is often included on the packaging. Otherwise, use a 5/32-inch bit for concrete screws that are 3/16-inch in diameter. Use a 3/16-inch bit for 1/4-inch screws. Keep spare bits in the correct size on hand. Working with masonry can wear out a bit faster and result in badly drilled holes.

The first step is measuring where you’ll be drilling. To do this, use a tape measure to find the right location and set the diameter of the hole. Use a carpenter’s pencil  to mark the spot on the concrete. Double-check the placement of the holes. If you’re drilling the holes to hang or install something, hold the item up and ensure the holes are lined up. Verify the holes are set so the piece you're installing will sit level against the concrete surface.

Whether you’re drilling into a concrete wall or floor, you’ll want to prep the surface and the surrounding area. Clear the space where you’ll be drilling of any furniture or household items. Sweep or vacuum the area. Remove any cobwebs or dust. Wash the surface to remove any dust, debris or dirt. Starting with a clean canvas helps you avoid problems later on.

Don’t let a concrete wall or floor stop you from completing your project. Working with concrete walls or flooring is a specialized skill. When you're equipped with the right tools and know-how, drilling into concrete will be a quick, efficient task.

A friend of mine who has been a pro engineer for 40+ years called round, and while he was here had a little play. He was also impressed and found them an 'interesting' tool and although he mostly uses insert tips stated there would be times when he would use such.

When drilling into concrete, be sure to wear the appropriate personal protection equipment. You’ll need eye and hearing protection, work gloves and a dust mask. If you are drilling many holes, it would be best to use vacuum dust extraction as well. The silica dust produced by drilling concrete is hazardous to your health, if inhaled.

Before you begin drilling into concrete, gather all of the supplies and materials you’ll need in one place. Making sure you have everything you need ahead of time helps you avoid delays mid-project. It also helps you stay safe while working. Make a list of the tools, supplies and materials you’ll need for your project and bring them to the work area. For this project, you’ll need:

I used a round tool bit for turning the crankshaft of the Stuart engine build I have on the go. – The finish on it is great.

Mazak's machine tool continues to evolve by multiple technologies such as process integration by five-axis multi-tasking, gear machining, grinding, and laser.

I remarked that although I was pleased with them they were expensive. He disagreed with me and thought them to be very good value.!!! – Different scale of priorities and viewpoint I suppose.

This has now become the standard tool of choice. Nearly as good as replaceable tip, (better at interrupted cuts), easy to set to centre height (using a gauge), and a lot cheaper than T.C. tips.

You are right Vic in that the tangential tool is very easy to adjust for height. The essence the QCTP however is in the C hange part. Whilst I use the tangential tool for much of the time other tools are more tricky to get right. Once the boats are set up then tool changes are quick and easy.

They come in 3 sizes… 8 – 9.5 – 12mm ( so it says in the advertising blurb ) so you can get on to suit all size machines, I got the 9.5mm for my machine & as said it's good albeit expensive, if you have a mill then you can make one, there is a thread on here that deals with these cutters & some have links to drawings to make one.

Experts recommend using a hammer drill with masonry drill bits or concrete diamond point screws for drilling into concrete. Hammer drills are designed to hammer while rotating to effectively drill into concrete.

Hammer drills usually have stop bars. You use a stop bar to set an exact depth where you want the drill bit to stop. To set the stop bar, follow the drill manufacturer’s recommendations. Next, fit the hammer drill with a carbide masonry bit in your desired size. Whenever you are actively drilling, wear safety goggles, gloves and ear protection.

I couldn't justify the cost for what I do so I've stuck with the four way though. I've got round the quick change part by bonding shims of the right thickness to the bottom of my insert holders so the're permanently on centre. Good plan except I noticed one of the shims had dropped off of one during last years house move! I think perhaps I didn't degrease it properly when I epoxied it. Oh well, another little job to add to the list!

Avoid drilling into concrete that has infrastructure behind it. Drilling where there are water pipes, electrical wiring or ductwork can be dangerous and cause damage.

OK Neil what's a Wimberly holder??, I have both lh & rh diamond tools and they'r great as above I use them for 90 percent of my work I bought 1 in ozz & the other by post & the customs stiffed me £20 !! that was before you could purchase them in this country.

Hi Nick, they are good, I splashed out for one & use it for about 98% of my machining needs, Brass, Steel, Aluminium, although you really need a chip breaker in the tool for this stuff as it comes off in long slivers.. very sharp! so I tend to use a carbide or HSS bit with chip breakers in for Aluminium.

If you are drilling a hole to attach a bracket or similar object to concrete by use of concrete screws, you will often find the correct size drill bit is often included in the pack. Otherwise, get a 5/32-inch bit for concrete screws that are 3/16-inch in diameter and a 3/16-inch bit for ¼-inch screws. Be sure to keep spare bits in the correct size on hand as working in masonry can wear out a bit quicker and result in improperly drilled holes. If using concrete anchors or shields, follow the manufacturer’s recommendations. In some cases, epoxies or other adhesives are used and a specific bit diameters may be noted based on these variables.

Sorry Vic, missed your post, 30 deg for the jig it is, thanks for that. Will make a toolholder in the fullness of time, that is, just as soon as I can get to it on the work list!

I did purchase left and right handed tools along with the grinding jig. I must say I am very pleased with them and the finish they give.
