Do I need lubricant when drilling with HSS Silver & Deming bits?
Yes, in metals — cutting oil will extend the life of the bit and improve hole quality.
Do I need lubrication when drilling with reduced shank bits?
Yes, especially in metals. Cutting oil reduces heat, prevents premature dulling, and extends bit life.
Do masonry drill bits go blunt?
Yes — they wear over time, especially when used on very hard materials or without cooling.
Do reamers come in different shank types?
Yes — including straight shank, tapered shank, and hex shank to fit different drills, reaming machines, and impact wrenches.
Do reamers need lubrication?
Yes — cutting fluid or lubricant extends tool life, improves finish, and helps with chip removal.
Do reduced shank drills come in different sizes?
Yes — common reduced shank sizes include 1/2" and 3/8" shanks, with cutting diameters much larger than the shank.
Do Silver & Deming bits have flat spots on the shank?
Yes — many have a 3-flat shank to prevent slipping in the chuck.
Do taper shank drill bits need lubrication?
Yes, when drilling metal. Lubrication reduces friction, heat, and wear.
Do taper shank drill bits slip in the socket?
When properly seated and clean, they rarely slip. If slippage occurs, clean both the bit shank and the spindle socket.
