A fast spiral drill bit is used in high feed rate applications under low spindle speeds, where removal of a large volume of chips is required. Use for drilling soft materials such as Aluminum.
Applications:
- For drilling operations in low tensile strength, softer materials that may pose problems with chip removal
- Typically the materials drilled with these drills are softer ferrous metals and alloys, such as soft steels and soft cast iron and soft non-ferrous metals and alloys, such as aluminum, magnesium, copper and zinc alloys
- The drills feature a combination of fast spiral and high helix angle as well as the wider flutes provide very efficient chip movement and ejection
- For many different applications with hand held manual drills and either portable or stationary machine tools
- Lubricating/cutting oils or the appropriate coolant fluids are recommended to achieve the optimal performance and the best tool life
- Right hand (clockwise rotation) cutting direction
- Standard two flute design with wider flutes
- Fast spiral, high helix flutes
- Helix angle: 34°- 40°
- Straight shanks that correspond to drill diameter
- The length of each drill is variable and is determined by the specific drill diameter offering the best balance between overall drill rigidity and depth capacity for each drill diameter
- Manufactured from high speed steel
- Precision ground flutes
- Cylindrically ground
- General purpose drills for soft materials
- 118° point angle and standard web thickness
- Bright finish
