To get the best bang for your buck when drilling into 3mm Mild Steel Flat Bar using an ONSITE+ Step Tip Drill Bit 5.5 – 8.0mm, the Alpha recommendation is using a Cordless Impact Driver.
In-house Alpha expert and product experience technician, Joel, has tried and tested the Onsite+ Step Tip Drill Bit range so he can offer the most accurate and relevant recommendations and instructions for you.
The purpose of this testing was to find whether an impact driver would produce the best results in specific materials, by seeing how many holes a 8mm Onsite+ Step Tip Drill Bit would drill before blunting.
