If you drill stainless steel or other hard metals, bit choice matters. The PATIKIL 33/64″ jobber bits are made from M35 high-speed steel with 4.50%–5.50% cobalt content, aimed at delivering strong heat resistance, wear resistance, and durability during demanding holes.

This set includes three matching 33/64″ (13.1mm) bits, each with a 135° split point to help the bit start more accurately. The gold finish is designed to improve corrosion resistance and extend service life.
For best results, keep the bit positioned at 90° to the work surface, use cutting fluid, and reduce speed/feed as material hardness increases. When drilling thicker stock, use multiple passes to help prevent overheating or breakage; for larger holes, start with a guide hole.
- 3-pack of 33/64″ (13.1mm) jobber drill bits; 100mm (3.94″) flute length and 150mm (5.91″) overall length
- M35 high-speed steel with 4.50%–5.50% cobalt content for hardness, heat resistance, and wear resistance in hard materials
- 135° split point tip for more controlled starts
