Metallics SD131812 – Frequently Asked Questions
1) What hole sizes does the Metallics SD131812 step drill bit cut?
The SD131812 is a 13-step bit covering 1/8 inch through 1/2 inch in one tool, so each step up the cone opens the hole to the next size without swapping bits. That range handles most low-voltage and control wiring knockouts in thin material.
2) Will a 1/8 to 1/2 inch step bit drill a hole for 1/2 inch conduit?
No. The SD131812 tops out at a 1/2 inch hole, which is the conduit's trade size, not the knockout diameter a 1/2 inch connector needs. For conduit knockouts step up to a larger-capacity step bit or a knockout punch set; use this bit for wire pass-throughs, screw clearance, and small device holes in the 1/8 to 1/2 inch range.
3) Is a spiral flute step bit better than a straight flute for sheet metal boxes and enclosures?
The spiral flute on the SD131812 clears chips up and out of the hole as it cuts, which keeps swarf from packing in the step and helps the bit pull a cleaner edge in thin sheet metal and enclosure panels. Straight flute step bits cost less but tend to load up and chatter more in gauge steel.
4) How many drill bits come in the Metallics SD131812 and how is it packaged?
One bit per order, supplied in a pouch rather than a case or index. If you are stocking service vans or a tool crib and want several, order by the piece.
