MaxTool Jobber Drill Bits Editorial Review
MaxTool 29-Piece Twist Drill Bit Set 8% Cobalt M42 Jobber Length Fully Ground for Hardened Steel Metal Cast Iron Sizes 1/16 to 1/2; JBS42G10R029P is a robust drill bit set that impresses with its hardness and cutting efficiency, able to reach HRC64, making it suitable for tough materials like hardened steel. Users rave about how effectively these bits slice through metal, likening their performance to cutting 'like butter.' However, a few reviews noted that some bits may break under pressure, but sharpening them can restore functionality. Additionally, the straight shank design lacks a 3-angle cut which raises concerns about chuck security during use. Overall, this set shows great quality and versatility.
