Does Anyone Know What Kind of Tip This Is?

It looks like a driver shaft tip for maybe a fitting kit?

At first glance it kinda reminds of a very old Cleveland adapter. Like 2015 era Cleveland.

I used our AI overlords to answer this question. 

Why this points to Mizuno

Looking closely at the adapter in your image:

1. “RH” engraving

• Mizuno adapters explicitly mark RH / LH on the sleeve
• Most other OEMs (TaylorMade, Callaway, Titleist, Ping) do not engrave RH/LH this way on the adapter itself

2. Loft marking style

• Mizuno prints the actual loft (e.g., 9.5 / 10.5) directly on the sleeve
• Other brands tend to use:
  • Callaway → “+1 / −1 / N / D”
  • Titleist → A1, B2, etc.
  • TaylorMade → ± with upright/standard indicators
  • Ping → line/dot system

3. Adapter geometry

• Flat-sided, hex-like aluminum sleeve
• Minimalist engraving
• Black ferrule transition
  This matches Mizuno’s Quick Switch hosel design.

Likely Compatible Models

This adapter style is used on Mizuno drivers such as:

• ST180
• ST190
• ST200
• ST-Z / ST-X
• JPX 900 / 919 drivers (not fairways)

⚠️ Mizuno fairway woods use a different adapter, so this is driver-only.
