Metallics HSSBG3164E – Frequently Asked Questions
1) What does the 135 degree split point on this Metallics drill bit actually do for me?
The 135 degree split point self-centers, so the bit starts where you put it without walking and without a center punch. That is the difference on hard, slick surfaces, drilling a panel face, strut, or structural steel overhead. A standard 118 degree point will skate on the same material. The split point also cuts with less thrust pressure, which matters when you are drilling 31/64 inch by hand.
2) Will the Metallics HSSBG3164E fit a standard 3/8 inch drill chuck?
No. At 31/64 inch, this is a straight-shank jobber bit whose shank on this size class exceeds 3/8 inch capacity, so it needs a 1/2 inch chuck. Most corded drills, hammer drills in rotary mode, and heavy duty cordless drills take it; a compact 3/8 inch driver will not.
3) What is the difference between a jobber length bit like this and a screw machine or aircraft length bit?
Jobber length is the general purpose length, long enough to drill through typical plate and channel but short enough to stay rigid. If you are working in a tight enclosure or a panel with no clearance, a screw machine (stub) length bit in the same 31/64 inch size is the better pick. If you need to reach through a deep assembly or past an obstruction, go to an aircraft length extension bit. Same hole, different reach and rigidity.
4) Is the black and gold finish on this HSS bit just cosmetic, or does it mean something?
It is a surface treatment, not paint. The black and gold combination on high speed steel is a black oxide plus bronze oxide finish, used to hold cutting lubricant and cut galling and heat buildup when drilling steel. It is a steel-drilling bit, not a masonry bit, and it has no carbide tip, so keep it off concrete and block.
5) How do I order the Metallics 31/64 inch black and gold jobber drill, and does it come as a set?
Order it by part number HSSBG3164E. It is a single 31/64 inch bit, not an index or a set, so if you want other sizes in the same black and gold 135 degree split point line you order each size on its own part number.
