Mark-III Dust Buggy
Part Number: SX13700
The Mark-III is a high performance; high precision saw designed to clean out control joints, remove the old joint filler, and make straight, accurate cuts in concrete up to 2″ deep. A specially designed blade guard allows the operator to see the blade yet still covers 98% of it for excellent dust control and a high degree of accuracy. The handle and frame are designed for more stability and adjustable height that rotates to get closer to walls or racks.
The aluminum alloy chassis has a lifetime warranty and is powered by a 120V 15 amp Metabo 24-230 (6,600 RPM).
The Mark-III uses 7 or 8″ blades up to 3/8″ (.375) wide, blade depth is fully adjustable and has a depth lock to prevent overcutting.
1. How deep can this saw cut?
2″ Maximum depth with an 8″ Blade. 1.5″ with a 7″ blade. The depth will be reduced as the blade wears.
2. Can this saw remove polyurea?
Yes, using the Tigertooth blade is recommended.
3. What kind of production can I expect?
New construction joint cleanout: 50 ft a minute.
Polyurea removal: 3-6 feet a minute @ 1/2″ depth, .125 joint width depending on several variables, faster if your only going 1/4″ deep.
4. Can this be used as an early entry saw?
Yes and no, it works fine if you cut the day after the slab is poured but it is not recommended for cutting freshly poured concrete.
5. What kind of vacuum do I need?
OSHA states you need 25 CFM (cubic feet per minute) of vacuum for every 1″ in diameter of the blade, so a vacuum that has a minimum of 200 CFM is needed. A “Big Box Store” wet/dry vac is not going to be sufficient.
6. What kind of blades can I use?
Any 7″ or 8″ blade that has a 7/8″ arbor hole and is rated for at least 7,640 rpm.
