Description
YG-1 TTF20708R YG Tap Chip Breaker Internal Coolant TiN HSS-PM Spiral Flute Tap M20 D8
L. Dewitt's SKU #: TTF20708R | Mfr Part #: TTF20708RLong chips can turn blind-hole tapping into a slow, risky operation. YG Tap Chip Breaker taps help shops solve long chips, bird nesting, chip packing, tapping torque, tool wear, overfeeding risk, broken taps, and inconsistent thread finish with chip-breaker flute geometry, a 15 degree helix, HSS-PM toughness, and TiN wear resistance.
- CNC machinists and programmers tapping blind holes in steels where long chips or bird nesting slow the job down.
- Production teams trying to reduce tap breakage, torque spikes, downtime, and inconsistent thread finish.
- Tool crib and purchasing teams matching taps by EDP, thread family, pitch limit, chamfer, coolant style, and thread size.
- Job shops and MRO buyers standardizing practical troubleshooting taps for non-alloy, alloy, high-alloy, and tool steels.
TTF20708R: YG-1 TTF20708R YG Tap Chip Breaker Internal Coolant TiN HSS-PM Spiral Flute Tap M20 D8 is a YG-1 HSS-PM spiral flute tap for blind-hole tapping where long chips, bird nesting, torque, and thread finish need to be controlled. Use this tap when chip control, blind-hole reliability, and thread finish matter more than simply cutting a thread.
Why This Model
Choose this model when the application calls for blind-hole tapping where long chips, bird nesting, torque, and thread finish need to be controlled. The chip breaker design is built to create shorter chips, improve chip evacuation, reduce friction, and support reliable thread finish in steel tapping jobs.

What This Solves
- Shorter, more manageable chips. Chip breaker flute geometry helps reduce bird nesting and chip packing in blind holes.
- Lower tapping risk. HSS-PM toughness and TiN coating support wear resistance, torque control, and reliable thread finish.
- Faster replacement matching. Thread size, pitch limit, chamfer style, coolant style, and series are grouped for clean purchasing decisions.
- More stable steel tapping. Built for non-alloy steel, low alloy steel, high alloy steel, and tool steel where conventional taps may struggle with chip control.
Common Applications
- Blind-hole tapping up to 2xD in CNC machining centers and production tapping operations
- Non-alloy steel, low alloy steel, high alloy steel, and tool steel applications
- Jobs with long chips, bird nesting, torque spikes, chip packing, thread finish problems, or tap-breakage risk
- Metric, UNC, and UNF replacement workflows where pitch limit, chamfer lead, and coolant style must be verified
