When it comes to professional concrete cutting and drilling the team at Diamond Products leads the way in many categories, from Concrete Core Bits, Walk Behind Concrete Saws, Diamond Blades and of course Core Drilling Rigs. The Diamond Products Core Bore name is who the pros call any size coring jobs, up to 60″+ diameter no problem. For 2” to 14” coring the Milwaukee Core Motors have been the standard for many years, relatively unchanged these 2 speed motors are real workhorses and you can find them mounted on any number of rigs from Core Bore as well as many other rig manufacturers. Diamond Products is launching two new Core Bore motors which look to change the game in core rigs with the CB733 (3 speed, 115v) and CB744 (4 speed, 220V). (more…)
At the World of Concrete this week one of the big cordless launches from Makita Tools is their new Brushless 7-1/4” Circular Saw (XSR01Z bare & XSR01PT kit) which utilizes two 18V LXT batteries to produce 36V of power. This is the First Cordless Rear-Drive circular saw on the market, although not claiming a Worm Drive or Hypoid Gear system, it does offer more power, 5100RPM, better balance and larger capacity (2-9/16”) vs other corded and cordless competitors.
We will continue to search out concrete tools and accessories to help our audience meet the upcoming OSHA Silica Dust standards, June 23, 2017. Cutting concrete outdoors with a gas cut-off saw and water hookup probably won’t change much however for indoor concrete cutting or dry cutting we will definitely see some new challenges. These new Core Cut C14 ($599) and C16 ($999) Concrete Saws are electric but offer serious power much closer to gas than we have seen in the past and can be used wet or dry. Many 14”+ electric saws currently don’t have water hookups or dust collectors and aftermarket attachments can be questionable. The new OSHA spec for dust collection require near HEPA filtration, automatic filter cleaning and 25 CFM per 1” of blade diameter in cutting. For a 14”saw that’s 350 CFM, you’re not going to find that at your local hardware store.
For November & December there are some very aggressive Milwaukee Deals designed specifically to put M18 9.0Ah batteries into your hands. The 48-11-1890 sells for $200, it’ll probably stay that price all next year and we think it’s well worth it but you’d be crazy to buy one. Only a few years ago Milwaukee was a small fry in the cordless game, they got aggressive to become top potato these days but competition is now heating up with many others. Milwaukee solution, 9.0Ah batteries for EVERYONE!!!
One great way into a couple larger batteries is the M18 FUEL miter saw 2734-21HD ($599), which will come with 1 battery normally but for the next couple months or until they all sell out you’ll get 2x of the 9.0Ah monsters. Weight obviously plays no part in how this tool functions so it’s a great partner for the bigger batteries but honestly this saw will work for hours on even a 5.0Ah. (more…)
**** OSHA UPDATE 4/7/2017 – New OSHA Deadline is September 23, 2017 for Silica Dust Compliance as there was a 90 day extension added.
As the deadline for implementation of OSHA’s new Silica Dust Rule changes grows ever closer (June 23rd, 2017) the question “how do you know if you are ready” is a growing concern. We have teamed up with the safety consultants from Safex to get some more information on the new Silica Dust Rules and other common safety questions for the jobsite. We will be doing a video series “On the Job Safety Tips with Safex” and if you’ve got any topics you’d like us to address in the future please suggest a topic here or like someone else’s idea if it’s already there. Below are just a few of the questions we’ve been hearing on the silica dust topic.
With Bosch selling the Skil brand to Chervon (Parent tool manufacturer behind EGO, Flex and many others) we were somewhat concerned as the SKILSAW brand has done a great job recently of separating itself out and re-branding towards the professionals again. There have been a handful of new tools built off it’s WormDrive technology including the WormDrive 10” Table Saw ($379), Outlaw 8” Metal Saw ($319) and SawSquatch 10-1/4” Saw ($399). It looks like a couple of things will be continuing, first the focus on new professional tools built off their trademark WormDrive platform and second the ridiculous names for every new saw will continue on as well! Launching January 2017 is the MeduSaw 7” Concrete Saw SPT79-00 ($399) it uses the WormDrive motor, also has built-in skate, guide, water hookup and dust collection.
When it comes to drilling, grinding, cutting or working with concrete in general, times they are a changing. It used to be acceptable to kick up clouds of silica dust and people just dealt with it. Not the case anymore and even on many the jobsite this is just not tolerated. When it comes to drilling holes in concrete whether overhead, horizontally or vertically this can be create a bit of a mess but the Bosch SDS-MAX SpeedClean and SDS-Plus SpeedClean carbide bits offer several advantages above and beyond just a cleaner, safer work environment.
Everyone knows when you pour fresh concrete you need to build-in control joints so that if/when the concrete is stressed there is a controlled path for how the concrete will crack. This is the common practice but there are several ways which those concrete joints are installed. “Early Entry” saw cutting is method which refers to cutting while not fully cured or 2 – 10 hours after being poured. Husqvarna Soff-Cut is a well know name for Early Entry cutting but there a couple new kid in town from Diamond Products Core Cut with First-Cut Early Entry Saws. Of course they’ve got several reasons why their saws are best.
The World of Concrete is just a couple weeks away and one of the most functional but underutilized concrete tools is the Concrete Chain Saw. The down side for these saws is that the chains are a bit pricey, we won’t disagree it is definitely cheaper to use a standard circular diamond saw blade. However a handheld 14” cut-off saw ($699-$1199) can only cut into material with a depth of 5”. The smallest (& cheapest) diamond chainsaw 680ES-12 ($1399) can actually cut a full 12” depth of concrete and these saws can go all the way up to 25” cutting depth. It can be a little misleading, side by side, 14” cut-off saw next to a 14” chain saw, while the measurements in the titles are the same these tools are very different. (more…)
