How do you maintain a reamer?
Keep it sharp, avoid forcing it, use proper lubrication, and store it in protective sleeves to prevent edge damage.
How do you maintain taper shank drill bits?
Keep the shank and socket clean, store bits in protective holders, and resharpen as needed to maintain cutting performance.
How do you prevent an extra long drill bit from wandering?
Start with a short pilot hole using a standard-length bit, then switch to the extra long bit for full depth.
How do you remove a taper shank drill bit?
Use a drift key (wedge-shaped tool) inserted into the spindle’s slot to knock the bit free.
How do you sharpen a Silver & Deming drill bit?
They can be sharpened on a bench grinder or with a dedicated drill bit sharpener, keeping the correct cutting angles.
How do you store extra long drill bits?
Use protective sleeves, racks, or cases to prevent bending and tip damage.
How does a percussion core drill work?
It uses a hollow, heavy-duty bit with a diamond or carbide edge, combined with hammering action, to grind and chip away material around the hole perimeter.
How long do annular cutters last?
With correct feed, speed, lubrication, and material matching, a quality cutter can last dozens to hundreds of holes before resharpening.
