For small holes, a gentle finger-twist of a slightly larger-size twist drill over the hole is usually enough to break down any sharp edges. For the deburring of larger holes, a handheld deburring tool offers the quickest and easiest way to clean up jagged edges.

Similarly, you may ask, what does a metal drill bit look like?

Bits designed to drill metal have flutes that taper to a point at either a 118- or 135-degree angle. Bits with a 118-degree point are general-purpose bits, while those with a 135-degree point are self-cleaning, which means they shed shards of metal instead of allowing them to accumulate around the shank.

Beside above, can I use wd40 for drilling metal? WD-40 is not a lubricant. It is a Water Displacement (WD) coating to prevent rust. Look for a dedicated drilling and tapping fluid like Tap Magic. I like the Sulphurated oil, especially for Titanium, but it is messy.

Likewise, people ask, how do you properly drill a hole in metal?


  1. To start your hole in metal, use a sharp scriber AND SCRIBE THE INTERSECTING LINES JUST ONE TIME.
  2. Examine the punch mark in a bright light and if necessary "drift" (tilt the punch) the punch mark over (using the fine punch) to get it in exactly the right place.
  3. Use a small bit to drill a pilot hole.

A good bi-metal hole saw will easily cut through softer materials, such as plastic and wood-based items, as well as harder materials, such as steel and stainless steel. In addition to using high speed steel with cobalt, the heat treatment process used by the manufacturer will impact the life expectancy of the hole saw.
