Minerallac 59914 – Frequently Asked Questions

1) Can the Minerallac tungsten carbide masonry bit be used in a hammer drill or rotary hammer?
No. The Minerallac tungsten carbide masonry bit is a rotary-only carbide drill bit, meant for portable rotary drills and drill presses at speeds up to 1000 RPM. Running it in hammer mode or an SDS rotary hammer is outside what it is built for. If you need hammer action for concrete, you want an SDS-plus shank hammer bit instead, which this straight shank will not accept.
2) What sizes does the Minerallac 3/8 inch masonry drill bit come in?
Two lengths, both 3/8 inch diameter: 3/8 x 4 inch (part 59914) and 3/8 x 6 inch (part 59916). Same tungsten carbide point and straight shank on both; pick the 6 inch for deeper holes or where you need the extra reach past a stud or box, and the 4 inch where you want less flex and better control.
3) Is this bit good for drilling anchor holes in brick and block for electrical mounting?
That's the work it's made for. The tungsten carbide point handles brick, block, and masonry, and 3/8 inch is a common anchor hole size for strut, straps, and box mounting. Keep the drill at or below 1000 RPM, run it perpendicular to the surface, and use steady pressure rather than speed. For hard poured concrete with aggregate, a hammer drill with an SDS bit will cut faster.
4) Why is my carbide masonry bit burning up, and am I running it too fast?
Most likely yes. This bit is rated to a 1000 RPM maximum; most cordless drills on high gear spin well past that, which overheats the carbide and dulls it. Drop into low gear or dial the speed down, let the carbide scrape rather than spin, and pull out periodically to clear dust from the hole. Heat, not pressure, is what kills these points.
5) What is the Minerallac masonry bit made of, and does the carbide tip come as a separate insert?
The body is steel with a black oxide finish and a gold head, and the cutting point is tungsten carbide. It ships as a single-piece bit, one per pack, so there is nothing to assemble or braze on. The black oxide helps with corrosion resistance on a bit that lives in a damp gang box.
6) Where is the Minerallac masonry drill bit made?
Taiwan. That matters to anyone running a job with country-of-origin reporting or buy-American style procurement rules, so it is worth checking against your spec before you standardize on it for a public project.
