YG-1 B2166 YG Tap INOX TiN Spiral Flute Modified Bottoming Tap 4-40 H6
L. Dewitt's SKU #: B2166 | Mfr Part #: B2166Stainless steel rewards the right tool and punishes the wrong one. YG-1 INOX tooling helps shops solve work hardening, torn threads, chip packing, tap breakage, poor finish, and slow stainless threading decisions with geometry, coating, and application focus built for stainless work.
- CNC machinists and programmers selecting stainless-specific tapping or drilling tools by size, coating, depth, and hole type.
- Production teams trying to control heat, work hardening, chip evacuation, finish, and tool life.
- Tool crib and purchasing teams replacing INOX SKUs by EDP, thread size or drill diameter, coating, and application family.
- Job shops and MRO buyers standardizing practical stainless tooling for repeatable threading and holemaking.
B2166: YG-1 B2166 YG Tap INOX TiN Spiral Flute Modified Bottoming Tap 4-40 H6 is a YG-1 stainless steel tap for stainless-steel threading where chip control, thread finish, and tool life matter. Use this tap when the setup needs stainless-focused geometry, clear replacement matching, and practical production reliability.
Why This Model
Choose this model when the application calls for stainless-steel threading where chip control, thread finish, and tool life matter. The INOX family is designed around stainless-steel chip control, finish quality, and tool-life planning, so the practical advantage is less trial-and-error and a clearer path from quote to spindle.

What This Solves
- Better stainless decisions. Size, style, coating, substrate, and application details are organized for fast replacement checks.
- Controlled chip behavior. Match hole type, coolant, geometry, and material condition to reduce packing, heat, and work-hardening risk.
- Cleaner production workflow. Stainless-specific tooling helps reduce avoidable setup changes, scrap risk, and rework.
- Results after use. Shops should see cleaner thread formation, better chip control, improved tool-life planning, and faster tap selection for blind or through holes.
Common Applications
- Stainless-steel threading where chip control, thread finish, and tool life matter
- Stainless steels up to 28 hrc and other gummy, work-hardening alloys
- CNC machining centers, toolroom work, production stainless jobs, maintenance machining, and repeat replacement programs
- Applications where exact EDP, size, coating, geometry, coolant, and material condition must be verified before ordering

Common Questions
What is the YG-1 B2166?
B2166 is a YG-1 INOX stainless steel tap used for stainless-steel threading where chip control, thread finish, and tool life matter.
Why use INOX tooling in stainless?
Stainless steel tends to work harden and hold heat, so geometry, coating, coolant, and chip evacuation need to be matched more carefully than in easier steels.
What results should this product support?
When selected correctly, it supports cleaner starts, better chip control, improved finish, and more predictable tool life in stainless applications.
How do I confirm the correct replacement?
Match EDP B2166, size, coating, substrate, hole type or drill depth, coolant strategy, holder/runout, work material, and programmed cutting data before ordering.
