Metallics HSSBG1564E – Frequently Asked Questions
1) Is a 15/64 drill bit the right pilot for a 1/4-20 tap?
No. A 15/64 inch bit is the standard tap drill for 1/4-20 UNC threads only if you are cutting threads; for a clearance hole that a 1/4-20 screw passes through freely you need a larger bit. The HSSBG1564E is the 15/64 tap-drill size, so use it when you intend to tap the hole, not when you want the fastener to slip through.
2) Will a black and gold oxide HSS bit drill steel, or is it only for wood?
High speed steel with a black and gold oxide coating is a general-purpose metal-drilling bit, so it handles mild steel, aluminum, and brass as well as wood and plastic. The oxide finish resists heat and corrosion better than bright-finish HSS. For hardened steel or masonry you need cobalt or carbide instead, not this bit.
