Cordless Tool Update

The world of cordless tools continues to be a race to see who can come out with a bigger battery first and who can develop a tool with a more powerful motor.

Festool

From Festool, the new 4 in 1 drill features a four-speed gearbox which provides loads of torque for hogging out material with large diameter drill bits and then quickly switches over to deliver 3,800 RPMs to blast through concrete with its hammer drill functionality. Of course this features a brushless motor, as their drills have for years, with a 5.2 li-ion battery. The Festool 4 in 1 ingeniously combines a drill, hammer drill and impact all in one tool. In addition they have a new cordless track saw that beats all.

Bosch

Bosch has a new wireless charging system as well as a socket ready impact that will handle 1/2″ sockets turning out 1650 in-lbs of torque as well as your traditional 1/4″ shank bit tips. 5 and 6 amp batteries are now available.

 

5 AMP BATTERIES FROM DEWALT

DeWALT

With the increase of battery power to 5 amp and the “coming soon” 6 amp batteries, you are seeing cordless tools that just a few years ago were not even feasible. Dewalt has a new cordless miter saw with a vertical capacity for
baseboard against the fence of 3-1/2″, crown molding vertically nested of 3-5/8″ or crown or base lying flat. It will cut 8″ @ 90 degrees. In addition you’ll get a tig welder that runs on 120 volt power or an internal li-ion cordless battery allowing you to run about 15 sticks on a single charge in the cordless mode at 140 amps in the tig mode and weighs about 25 pounds, making it very portable.

 

Milwaukee

    • Milwaukee –With their latest Li-ion battery packs, Milwaukee doesn’t care about being first, they care about being the best.
    • Milwaukee Tool has a very strong following in the brushless motor world and will soon release their 2nd generation Fuel Brushless with a 18 volt hammer drill with a wrist twisting 1200 in lbs or 100 ft pounds of torque  and a 5 amp battery standard, a 2 speed gearbox topping out at 2000 r.p.m’s.
    • Next up will be a 6 amp battery and a 9 amp battery. Stay tuned. The 9 Amp should be a great upgrade for high draw tools, portaband-circular saw-hole hawg right angle drill-hand planer- mag drill-sds rotary hammer and the like but not really intended for a traditional drill or impact.
    • While it might not make sense to upgrade from a 4 to 5 amp battery, but  if you have some of the older 3 amp batteries that are loosing their power and  umph it might be time to upgrade your battery packs to the 6 amp when they arrive which will double your run time.
    • In addition Milwaukee Tool has come up with a way to get even more power from a brushless motor with increased efficiency of the magnets hence the 1200 in-pounds of torque in the generation 2 brushless tools.

 Be on the lookout for the 2897-22 due to start shipping in August 2015.

Do I Need a Hammer Drill or Rotary Hammer

Here on the gulf coast a hammer drill is of little use for drilling into a concrete slab because the rock used in the concrete is very, very hard just as it is in many parts of the country.
A hammer drill works with a larger number of blows per minute but it does not hit hard enough to break thru the rock used along the gulf coast.  It will however work fine in a  brick or cinder block wall.

A rotary hammer hits slower but with an impact force 2 to 3 times over a hammer drill.
One way to know the difference is a hammer drill has a 3 jaw Chuck where a rotary hammer has either a Spline drive or a sds-plus or a sds-max depending on the capacity and many rotary hammers have a three mode operation. Hammer mode for drilling in concrete, a rotation only mode for drilling in wood and a chipping mode for chipping concrete or removing tile and thinset mortar.

A hammer drill has two “hammer dogs” that mechanically “rub” together to make its impact.  Rotary hammers use pneumatic pistons to generate their impact energy, and don’t have metal-on-metal wear and tear.

Bosch is our preferred line of Rotary Hammers the Bosch  11255 VSR  is a great hammer for holes up to 1″ as well as removing tiles and light concrete chipping.

The rotary hammer will outlast even the best hammer drill and the bits have a better grade of carbide for serious concrete work.
