AMDS normally stocks SierraBlaster systems that include the stainless steel blast head unit. It is the most popular version and can be used in any orientation. However other versions are available and of course you may want to add more Blast Heads to an existing system. CONTACT US for more information on SierraBlaster blast head options.

There is an Aluminum version of the Blast Head unit. It is lightweight for applications where total system weight is a concern. Please note the Aluminum Blast Head is designed for vertical or near vertical orientations because a weight, such as a rock or a sandbag, must be placed on top. It is therefore of more limited use than the recommended stainless steel blast head unit.

This is also an optional Stainless Steel PiggyBack version of the Blast Head unit. It adds extra weight to the blast head to help contain and concentrate the effects of the blast. It is especially helpful for those who will be blasting in the horizontal or inverted orientations. If you already have a Stainless Steel Blast Head there is a bolt on PiggyBack Weight available as an add on accessory item.

A Blast Head is reusable and helps contain the explosion inside the material to be blasted so that the power is used to split the material instead of escaping out the borehole. Without the Blast Head the powerful 375 Magnum Cartridge will not develop to its full potential thus you have an important symbiotic relationship between the Blast Head and the 375 Magnum Cartridge. Remember if purchasing additional blast heads for your system you must also purchase a Blast Cord for each Blast Head.
