Review on 🔧 LudoPam Metric Cobalt Jobber Stainless: Premium Quality and Precision Tool for Professionals by Shaun Helm

I received this item in exchange for my honest review of the Revain Vine program. Seller's Brand: LudoPam lists them as "LudoPam 4mm Cobalt Steel M35 Jobber Length Spiral Drills for Hard Metal, Stainless Steel, Pack of 10." I've had to drill through tough stainless steel that traditional drill bits often can't handle. These bits are properly sharpened and made from cobalt steel so I can use them on CC. Shown is 1 set of 10 bits in a plastic box. Figure 2. Drilling a hole in a metal plate after making the initial punch mark to keep the drill bit from wandering. Figure 3: A clean hole drilled with a chisel. TIP: When drilling SS, use lower RPM (less than 600) and lubricating oil for drilling. I try to prevent heat build-up with less pressure on the drill. These things help! I was able to complete a project in SS with these cobalt steel drills, they are excellent. Be careful, wear eye protection, gloves are a good idea too. I highly recommend this 4mm Cobalt Steel LudoPam Drill Bit Set!
