Cordless Metal Cutting Circular Saw Blades

Some years ago Panasonic released a 12 volt metal cutting circular saw with a 4-3/8″ blade.  My first thoughts were this looks like an as seen on TV tool.  Then they started selling and fast.  These little tools were great for cutting mild steel like strut rod and EMT.  As a matter of fact, cutting threaded rod was now very easy as the tool left a clean burr free cut.  Later Panasonic released a larger 15.6 volt version as well.  Today you can find cordless metal cutting saws from DeWalt, Bosch, Makita, Milwaukee and many more.

The applications for cordless metal cutting saws include cutting EMT, ladder rack, basket tray, wall brackets and as mentioned earlier threaded rod.  HVAC installers many times use them for cutting duct.  The duct acts as a sound chamber hence the cordless metal cutting circular saws are often called “screamers”.   Cutting solid materials is loud but not near as loud as cutting hollow material.  Hearing protection and safety glasses are a definite requirement.

You can buy saws that are specifically metal cutting saws.  These tools feature more blade shielding which is important as the tools throw off a lot of tiny metal shavings.  An added consideration is that these application specific tools can match the RPM of the saw to the blade making for more efficient cuts.  If you already have a cordless circular saw or even a corded saw for that matter, metal cutting blades are readily available for mild steel, thin steel as well as aluminum and other non ferrous metals.  We handle cordless metal cutting blades from Tenyru.  Tenyru is well known for top quality circular saw blades and their metal cutters are no exception.  We are a full line Tenyru dealer so if you don’t see the blade your are looking for in our store, give us a call.

Cordless metal cutting saws are truly a nice little addition to your install tools.  As mentioned earlier you will find them from many of the top cordless tool manufactures.  Many of them offer a bare version of the tool to keep the cost down as you likely already have the batteries and charger.  Give one a try!


Core Drill Bits

SDS Max (TE-Y) Core Drill Bit

SDS Max (TE-Y) Core Drill Bit

If you need to drill holes in concrete larger than 1-1/4″ or so, your best bet is a concrete core drill bit.  Core drill bits are available for SDS plus hammers, like the Bosch Bulldogs and the Hilti TE-15,  and your bigger SDS Max (Hilti calls them a TE-Y) and Spline core hammers.  Bits for the SDS plus hammers are available in sizes up to 4-3/8″ and the SDS Max (Hilti TE-Y) and Spline bits are available in sizes up to 6″ in diameter.  Most have a drill depth of up to 17″ or so.  Most rotary hammer drills show a rating for what size core bit would be at the upper end of the capacity for the drill.  I know some contractors that do exceed the recommend size, the key is to work slow and let the tool do the work.  As you exceed the recommended size on a core drill bit, you over power the drill and the tool will tend to clutch out more often.  Core drill bits on rotary hammers tend to blow out the concrete as they come through the work surface.  If that presents a problem, you may choose to drill a pilot bit through the wall or floor and start drilling from both ends.   You can find core drill bits for your SDS plus, SDS Max and Spline bits at ConstructionFastening.Net  Not sure what bit your rotary hammer uses?  Give us a call toll free at 1-877-212-2377.

How do you suspend  grid wire or all thread from a concrete deck while standing on the floor if the the concrete is to brittle for your Ramset or Hilti tool or you simply are not allowed to shoot. For those times when you need to suspend a cable run or anything for that matter to a concrete deck that is just out of reach, consider the ODM overhead drill machine.  Designed to work with most D handle SDS rotary hammers, the ODM overhead drill machine extends to reach ceilings decks up to 13′.  The hands free probe trigger system allows you to keep both hands on the tool.  After you drill your hole, use the I Driver to drive in tie wire wedges or spikes with ceiling grid wire pre attached.  If you want to install threaded rod, simply drill the hole and then install a concrete Sammy Screw, with the threaded rod already attached using the Torque Master tool.  Think of the time savings over a lift that can be had in many situations.  Click here to see a video of the tool in use.

Extra Long SDS Hammer Drill Bits For Hilti, Bosch, Dewalt and Others

If you are faced with the challenge of drilling an extra deep or long hole in masonry, you know it can be a real challenge to find a hammer drill bit long enough for your SDS hammer drill.  Usually you can find a bit that will drill up to about a foot, but some projects, especially projects that are older buildings or additions will require you to drill deeper holes. Now what?  Be prepared.  We offer a full line of SDS bits from 3/8″ to 3/4″ diameters that will give you a drill depth of anywhere from 16″ to 34“!   If you need a whole a little wider, you can drill a pilot with the smaller diameter and then come from either side if possible.  We have bits 7/8″ diameter to 1-1/4″ that have 16″ diameters.  If you have an application that requires a larger hole, consider one of our thin wall cores designed for use with SDS hammers.  You will find a size range of 1-9/16″ to over 4”.  There thin wall design reduces the amount of friction allowing even small to medium size SDS hammers to handle up to  2-1/2″ hole or more with ease.

Is my hammer an SDS hammer?  Sometimes we get the question, especially with Hilti hammers, is my hammer an SDS hammer drill?  If it is a smaller hammer, likely so.  It can get confusing, with some brands.  For instance, Hilti calls the bits for SDS hammers a TE-CX bit.  An SDS shank hammer drill bit is about 3/8″ diamter and has to dimples opposite each other, and two slots opposite each other.  If that is what you have, any SDS bit will fit in to your hammer drill.  If the shank is about 3/4″ you likely have an SDS Max or possibly a spline bit.  These are typically bigger, and noticeably heavier tools.
