Metallics ED78 – Frequently Asked Questions

1) What size hole does the Metallics ED78 auger bit drill, and how long is it?
The ED78 is a 7/8 inch diameter bit with an overall length of 8-1/2 inches, so it bores a 7/8 inch hole and gives you enough length to get through a stud or joist and a bit of reach beyond. Both numbers come straight off the part description: Bit 7/8 x 8-1/2.
2) What does single spur, double cutter mean on an electrician's auger bit?
It describes the cutting head. The ED78 is a single spur, double cutter design: one spur scores the hole perimeter while two cutting edges clear the chip, which is the common configuration for boring wire holes through framing lumber. It is an electrical boring bit, not a general metal drill.
3) What is the part number to order the Metallics 7/8 inch boring bit?
Order it as Metallics ED78. That is the manufacturer part number and the only model on the item, so there is no size or finish option to specify beyond it.
