Precision HSS Twist Drill Set
The Alliance Tools Precision HSS Twist Drill Set represents the pinnacle of drilling technology for professional and industrial applications. Each drill in this comprehensive set is manufactured to exacting standards, ensuring consistent performance and exceptional results across a wide range of materials.
Superior Materials and Construction
Crafted from premium M2 high-speed steel, these drills offer an optimal balance of hardness and toughness. The M2 HSS composition contains carefully calibrated amounts of tungsten, molybdenum, chromium, and vanadium, creating a tool steel that maintains its cutting edge even under high-temperature drilling conditions. This material composition allows the drills to perform consistently when working with mild steel, aluminum, brass, plastic, and wood materials.
Precision-Engineered Geometry
Each drill features a precisely ground 135° split point design that delivers several key advantages:
- Immediate bite into the workpiece without walking or wandering
- Reduced thrust requirements, minimizing operator fatigue
- Self-centering capability for accurate hole positioning
- Improved chip breaking for cleaner holes and reduced clogging
Comprehensive Size Range
This set includes 25 drills covering the most commonly used diameters from 1mm to 13mm in precise increments. The complete size range includes: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, and 13mm.
Professional Finish and Treatment
The steam oxide finish applied to each drill serves multiple purposes:
- Enhanced surface hardness for improved wear resistance
- Reduced friction during drilling operations
- Superior chip evacuation through the flutes
- Increased corrosion resistance for longer tool life
Durable Storage Solution
The entire set comes housed in a robust metal case with individually sized slots for each drill. This storage solution not only protects the drills from damage but also allows for quick identification and selection of the required size.
