Dobco offers a versatile line of Hougen Rotobroach annular cutters

Hougen Rotobroach annular cutters, available from Dobco

Many manufacturing applications require cutting or drilling tools, but certain tasks need a specialized method of drilling holes through steel. This is where annular cutters come in handy. Dobco Equipment distributes an impressive group of Hougen Rotobroach annular cutters that fit different drills.

How do annular cutters work?

Annular cutters are drill bits designed for drilling holes through steel. Similar to hole saws for wood, these bits cut only the outside edges of holes. They also create burr-free holes to close tolerances without pre-drilling or step-drilling, and they require less force than other twist bits while creating larger holes.

Hougen Rotobroach annular cutters are built for many drilling applications, from thin sheet metal to thick plates. They cut more quickly with a better hole finish and last longer than standard bits.
