Features & Benefits:
• HSS Drill-Tap Combination Tool with 30° Spiral Flute, Metric, ISO Standard
• Combination of a core-hole drill and tap to produce a thread in one pass.
• This significantly reduces the time needed to produce the thread on site with the use of a hand-held power tool.
• There is no need for a tap wrench or tool change.
• Steam tempered surface acts to retain the lubricant and provide smoother cutting.
• Thread form: metric coarse
• Meets ISO Dormer standards
• DIN thread pitch diameter tolerance zone (high basic pitch diameter)
• Through hole application
• 1.5xD usable tool depth to diameter ratio
• High speed steel tool material
• Semi bottoming tap chamfer (2-3 pitch lead)
• Spiral flute geometry
• 30° helix angle (Flute)
• Right hand rotation/cutting
• Series E650
