Choosing the Right Spot Welding Drill Bit – Buyer’s Guide

Looking to buy spot weld bits for your automotive upgrade? We have a simple guide on what to look for. Have a look.
Drill bit diameter
Buying a whole set of drill bits has the benefit of flexibility in diameters. You can use the smaller bits as a centering bit before drilling with a specific diameter. 3/8” make exceptional holes when removing spot welds.
Quality of center bit
The centering bit should be in place to avoid bit walking. The right center bit with spring adjustments allows for high precision drilling and neat holes, eliminating the slips and wobbling. The springs serve to hold the bit in place while the cutters drill out the spot welds.
Sharpness of blade
You can alternate the blades, especially on double-sided blades when they lose the brutality. Rotating blades are so sharp that it takes a few minutes to remove a whole panel. If both sides lose sharpness, you need to replace the whole cutter blade.
Blades made of steel have high heat resistance thus a longer cutting span compared to other materials. Low heat resistance causes blunting of sharp blades.
High-speed steel and hard steel are the key component materials for these bits. Steel has high heat resistance compared to other metals which makes it suitable. Titanium and cobalt coated drill bits have high performance, durability, and heat resistance which makes them suitable for spot weld drills.
Quick Reminder: Spot weld drilling like any other requires that you take some precautions. Your safety is key and that means you should watch out for the following:
Drilling speed, lubrication, and eye protection where necessary. Ensure that no harm comes your way and that you maintain your tools’ service during the process.
