MIBRO High-Speed Steel (HSS) Silver & Deming Drill Bits are designed for creating large-diameter holes in materials that require more cutting capacity than standard drill bits can provide. Ideal for general-purpose drilling in wood, plastics, and most ferrous and nonferrous metals - including mild steel, cast iron, sheet metal, aluminum, copper, and brass - these bits deliver dependable performance for workshop and fabrication projects. Their reduced shank allows larger diameter bits to fit into drill chucks with a 3/8 in. (9.5 mm) capacity, making them a practical solution for drilling oversized holes. The 135° split-point tip helps reduce walking and eliminates the need for a center punch on many applications for faster, more accurate starts. Three flats on the shank provide a secure grip in the drill chuck to help reduce slipping during use. For best results, use these drill bits in a drill press at speeds up to 400 RPM. Not recommended for drilling high-grade or stainless steel.

Q: Can this be used on plaster?

1 Answer
  • A: Hi, it is not recommended to use Mibro 9/16 in. Silver and Deming Drill Bit on plaster, because plaster is highly abrasive and will quickly dull the bit's high-speed steel (HSS) edge.

    Don’t bother

    2 years ago
    This drip bit is junk. Never have I had a big drill bit bend. Bent drilling first hole. TSC mgr was great. Ask me what I was drilling, (mild steel). Mgr looked at it and was shocked. Mgr said aren’t drill bits meant to drill? Yep I said. Refund was given. Please stock a different, better brand of drill bits. Great mgr, poor product

    9/16" Drill Bit Review

    5 years ago
    Drill Bit was exactly what I needed. It work great and the quality was good.

    Good value for the price of the bit.

    6 years ago
    Good bit if you pre-drill up to 1/2 inch and use this bit to take out the last 1/16. Only works on really mild steel.

    Yes, I recommend this product.
