  • Variants: Available in 3g, 6g and 9g charges.
  • Initiation Mechanics: Available in the Standard variant only.
  • Applications: Extremely sensitive blasting work. Typical application will be the breaking of concrete, small boulders in confined spaces or the splitting of rock.
  • Maximum blasthole diameter: 12mm (0.47 inch)

AutoStem Mini

17mm

(0.67 inch)

  • Variants: Available in 20g, 30g and 40g charges.
  • Initiation Mechanics: Available in the Standard variant only.

  • Maximum blasthole diameter: 20mm (0.79 inch)

AutoStem Generation |||

35mm

(1.38 inch)

  • Variants: Available in 100g, 180g and 300g charges.
  • Initiation Mechanics: Available in the Standard and Sequential cartridge variants.
  • Safety Switch: Standard cartridges contain a safety switch where Sequential cartridges do not.
  • Applications: Typical application will be the breaking of in situ rock found in civil construction, underground mining, secondary blasting, and demolition work.
  • Maximum blasthole diameter: 38mm (1.50 inch)

AutoStem Generation III

43mm

(1.69 inch)

  • Variants: Available in 350g, and 550g charges.
  • Initiation Mechanics: Available in the Standard and Sequential cartridge variants.
  • Safety Switch: Standard cartridges contain a safety switch where Sequential cartridges do not.
  • Applications: Typical application will be the breaking of in situ rock found in civil construction, underground mining, secondary blasting, toes and crests, and extreme demolition work.
  • Maximum blasthole diameter: 46mm (1.81 inch)

AutoStem Generation III

1 700g

(3.75 pounds)

  • Variants: 83mm (3.27 inch) and 87mm (3.42 inch)
  • Initiation Mechanics: Available in the Standard and Sequential cartridge variants.
  • Safety Switch: Standard cartridges contain a safety switch where Sequential cartridges do not.
  • Applications: Typical application will be benching in the opencast mining environment bulk excavations of situ rock found in civil construction and, shaft sinking. Deck load charging with in-hole spacing of 2.5 to 3.0m will be the norm across the length of the hole.
  • Maximum blasthole diameter: 89mm (3.50 inch) for the 83mm (3.43 inch) cartridge and, 102mm (4.0 inch) for the 87mm (3.43 inch) cartridge. It is recommended that a stemming device is used with this hole diameter.

All Standard cartridges except the micro cartridges feature a safety switch to prevent accidental initiation. Sequential cartridges, lacking a built-in initiation device, need an accessory detonator assembly to become operational and thus do not require a safety switch.
