We offer three versions of the Micro-Blaster™
MICRO-BLASTER™ I
The Micro-Blaster™ I is a compact and affordable demolition system utilizing a fast burning proprietary gas producing cartridge to crack rock and masonry. Operated remotely with a 25-foot pull cord, the Micro-Blaster™ I is safe and easy to use. Because of its low energy output, this system is usable in almost any environment. Requiring only a 5/16 inch diameter hole, 9 inches deep, the system can be employed without the need of expensive large hole drilling systems. Assembled using hardened tool steel components, the Micro-Blaster™ I provides many years of trouble-free use and is easily serviced in the field with common hand tools. Packaged in a durable and compact molded case (13.5 in.W x 10 in.D x 3.5 in. H), the Micro-Blaster™ Kit comes complete with a Micro-Blaster™, hole blower, hex key, bull pins (for wedging apart cracked rock), release cord assembly, and manual.Micro-Blaster™ I Instruction Manual
MICRO-BLASTER™ II
The Micro-Blaster™ II offers several improvements over the original Micro-Blaster. Triggered by a pressure pulse simplifying drilling strategy, freeing the user from the restraints of the lanyard activation of the original Micro-Blaster. Pressure sources can be either compressed air or CO2 cartridge technology. Intrinsic safety: The system cannot fire until remotely pressurized by the operator. Simultaneous firing of multiple Micro-Blaster II units which allows much larger masses to be cracked through the use of a manifold/valve assembly connecting multiple units. Simplified assembly/disassembly for easier and faster field maintenance. The Micro-Blaster™ II is a safe and economical system for the cracking of rock and masonry. Based on propellant technology, special blasting licenses are not required. The small size of the system allows it to be used in almost any location. Capable of breaking rock or masonry of almost any size by successive blasts, the Micro-Blaster II does its job with almost no fly-rock, which can be completely eliminated with the use of light mats. Pneumatically triggered from a 25-foot distance, the system can be configured to allow multiple simultaneous shots using a variety of pressure sources including CO2 and compressed air. The Micro-Blaster™ II is available in two versions, a single head kit as well as a triple head kit for larger projects. Requiring only a 5/16 inch hole at 10 inches deep, the system allows the use of inexpensive drilling equipment, which is often a major capital expense for demolition work. Designed for many years of trouble-free performance, the kit weights only 10 lbs. The durable molded case measures 15" x 12" x 6" and contains the Micro-Blaster™ II, a bore brush and bulb blower (for cleaning drilled holes), 2 tapered pins (for wedging apart cracked material), a CO2 bicycle inflator (for pressurizing the system), and instructions for safe use.Micro-Blaster™ II Instruction Manual
MICRO-BLASTER™ IIx3 (3 Head Kit)
Our most popular version, the Micro-Blaster IIx3 Kit contains three Micro-Blaster™ II heads and a three-way manifold/valve assembly to allow the simultaneous triggering of 1, 2, or 3 heads. This assembly comes with a small padlock and key to lock out the system rendering it unfirable between shots greatly adding to safety. The Micro-Blaster™ IIx3 will allow users to break much larger masses of rock or concrete than with just the single head models. Users will need to supply a source of compressed air or CO2 (minimum 75 psi, 7 gallon portable air tank recommended) to trigger their systems. If working in remote areas a "T" handle bicycle pump and our 1/2 gal aluminum air tank will allow for a very portable triggering system. Note that you will need to outfit your air source with a quick coupler (1/4" Industrial Interchange) to connect to the hose on the MB IIx3 Manifold/Valve to your air source. We offer a Micro-Blaster™ II Portable Air Tank. And, for those who already have their own air tank, we offer an Air Tank Conversion Kit in our accessories below. For more details about how this technology works read the paragraphs describing the Single Head Micro-Blaster™ II.Micro-Blaster™ Accessories
Micro-Blaster™ II Air Tank
When charged with 120 psi of air will reliably trigger three Micro-Blaster™ II Heads simultaneously. Easily recharged in the field with bicycle tire pumps between shots and provides extreme portability for working in remote areas.

Overall Dimensions: 8"Lx6”Dx7.25"H (228x152x184mm)
Maximum Pressure: 150 psi
Capacity: 0.5 gallons
Weight: 4 lbs.
Air Tank Conversion Kit
If you already have your own air tank you may need components to connect the Micro-Blaster™ to your tank. For your convenience we have put together a kit containing the above components. Ask your dealer or Ezebreak for the Air Tank Conversion Kit (Part# MBIIx3-ATCK) if you cannot easily find these components locally.
Detailed Instructions and Tips
Micro-Blaster™ Blow Gun Assembly
Other than drilling, the most tedious aspect to using your Micro-Blaster™ is the hole cleaning process. To speed up this operation we have developed the blow gun assembly. Equipped with a 1/4" quick connect plug (Industrial Interchange, same as our manifold hose connector), a 5 foot air hose, a lever valve, and a 9.5" long, 1/4" diameter stainless tube, the unit will quickly and thoroughly clear the dust from drilled holes in just one or two seconds. Since its use is intermittent, only a small compressor that is capable of 100 psi output is required for operation.
!!! SAFETY NOTICE !!! THIS BLOW GUN ASSEMBLY IS NOT OSHA COMPLIANT AS IT DOES NOT LIMIT PRESSURE AT THE NOZZLE TO 30 PSI. CARE SHOULD BE USED NOT TO DIRECT OUTPUT AT PERSONNEL. ALWAYS WEAR APPROVED EYE PROTECTION WHEN USING THIS AND OTHER EZEBREAK PRODUCTS WORK SAFELY AND CRACK WISELY!
Industrial Interchange to Schrader Fitting Adapter
This adapter will allow the firing of a single Micro-Blaster™ IIx3 head from an air source using a Schrader type chuck commonly found on tire filling devices. Portable air tanks, T-handle bicycle pumps, CO2 inflators are common examples. Complete with a Dust Cap.
SDS+ Drill Bits for Micro‑Blaster™ I & II
Many of our customers have had problems finding the proper 5/16" diameter drill bits for their Micro-Blaster™ Systems. We now stock 2 models which will produce the required holes. The shorter of the 2 models shown above will drill up to 12" deep holes for double cartridge shots and is marked with a red stripe at 10" from the tip for single cartridge shots. The longer bit pictured has the capability of drilling up to 16" deep which will allow users the option of using 1, 2, 3, or up to 4 cartridges per shot. This bit also has a longer lasting carbide tip which should give excellent service in even the hardest materials.
