The extended 45mm tip reaches through narrow mounting holes and hard-to-access spaces, helping you mark precise positions where ordinary markers cannot reach.

Standard markers often have bulky casings that get blocked by outer surfaces. Our ultra-slender 45mm metal sheath allows perfect clearance for deep-hole markings.

✓ 45mm extended stainless steel sheath easily clears deep mounting holes.
✓ Accurately positions markings on hidden underlying surfaces.
✗ Bulky plastic shoulders get blocked by mounting hole edges.
✗ Incapable of reaching underlying templates or deep points.
Instead of disposing of the marker when the ink runs low, easily restore your ink supply using the quick screw-cap refill design.

Unscrew the rear cap counterclockwise to open the ink chamber.
Fill with an appropriate amount of marker ink, then securely tighten the rear cap.

Formulated for demanding worksites. The premium oil-based ink dries rapidly to prevent smudges and resists water and fading, keeping your guides completely legible.

The rigid needle-nose metal sleeve holds the writing tip stable, preventing flexible bending when reaching through boards. The premium ink formulation also allows for up to 72 hours of cap-off time without drying out.
Whether you work with wood, plastic, glass, or metal, this versatile deep-hole marker delivers clean positioning guides in any professional or DIY environment.
