Jerax Tools Step Drill Bit Set 1/2, 7/8, and 1-3/8 Inch – M2 HSS, Straight Grooved, Double Fluted for Stainless, Aluminum, Copper, Wood, Plastic

Discover the Jerax Tools Step Drill Bit Set, a versatile trio designed to handle metal, wood, and plastic with a single, efficient tool. The stepped design enlarges holes progressively, reducing the need to switch bits and streamlining job sites from garages to workshops.

Crafted from M2 high speed steel, these bits emphasize durability and wear resistance. The formulation includes 50% more Tungsten and 150% more Molybdenum, paired with vacuum heat treatment and nitride surface hardening. This combination helps maintain sharpness and extend life through repeated drilling tasks on tougher materials.

Non-stop drilling with visible size cues

• Polished steps and size highlights let you see the target hole size as you work, keeping momentum high.
• No need to pause mid-drill to check measurements, which can save time on long runs or fabrication tasks.

Performance you can feel

• High-accuracy CNC processing combined with optimized design delivers faster, cleaner holes compared to standard bits.
• Double-fluted, straight grooves contribute to smoother chip evacuation and reduced resistance during drilling.

Versatility for a range of materials

• Heavy-duty cutting handles stainless steel, hardened metal, mild steel, galvanized steel, aluminum, copper, plastic, and wood.
• Specifically capable of drilling stainless up to 12 gauge (2.7 mm) thickness, adding to its multi-material appeal.

In real-world use, this set aids quick hole sizing in fabrication assemblies, cabinet installations, andDIY projects where multiple materials meet. While results vary by material and application, many users report faster setup, fewer tool changes, and cleaner hole edges when using these bits.
