The 75 Series is a boron carbide insert with a straight bore. The insert is suitable for blast guns and other holders with a cylindrical 3/4" insert format. Several bore sizes are available, from 1/8" (#2) up to 3/8" (#6), for fine to medium precision blasting and spot blasting.

Boron carbide typically provides five to ten times longer service life than tungsten carbide when used with aggressive abrasives, such as aluminium oxide and selected mineral abrasives. This makes the insert particularly suitable for applications where wear resistance and durability are more important than the lowest purchase price.

Boron carbide is more brittle than tungsten carbide — careful handling during installation, removal and use is required to prevent cracking.

Key Features

  • Cylindrical 3/4" insert
  • Does not screw directly into a standard blast nozzle holder
  • Recommended for aluminium oxide and selected mineral abrasives

Available Sizes and Lengths
Available in bore sizes 1/8" (#2), 3/16" (#3), 7/32" (#3-1/2), 1/4" (#4), 5/16" (#5) and 3/8" (#6), all with a length of 50.8 mm.

Good value for the money.
Size: 9.5 Wide, Color: Beige
Comfortable right out of the box. Great style and well made. The more you wear the softer they get but maintain their overall appearance.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
