Drilling Holes In Stainless Steel Sheet

As said further up, around 1200 rpm should be ok and plenty of cutting fluid/paste, and steady pressure so the drill bit is always biting into fresh material.

Drilling holes in stainless steel sheet.

The way to tell your drilling too fast is that it will make a high squealing sound, very annoying. Stainless steel is a tough metal and one of the most commonly used metals in the automobile industry. Will enable you to drill thin sheet metal.

The carbide teeth on these steel saws cut hard metal such as steel, stainless steel, cast iron, and titanium. I set my drill press to its slowest speed or run my portable drill as slow as the trigger will allow. Here is the right way to drill stainless steel:

Self drilling screws are designed specifically for drilling through thin sheet metal, and are available in a range of head types and drives.stainless steel self drillers are manufactured from 410 grade stainless steel which is harder than the 300 series grades. An easy fix for this is to clamp the workpiece, and start drilling the hole. Steve parente shows how to easily drill large holes in stainless with a step bit.

Drilling holes in steel requires sturdy bits with sharp cutting edges. Micro hole perforated metal are different than common hole size perforated metal. Step drilling is often recommended for thicker profiles of stainless steel to help keep swarf clear, allow for good penetration of coolant into the hole and to reduce friction at the drill point.

Exit holes down to 5 microns diameter. The thickness is 0.032 sheet metal, and the drill diameter is 0.191 (#10 tight clearance fit). Drilling stainless steel is not as difficult as you may thi.
