5/8" High Diamond Stained Glass Lapidary Glass Grinder Head Bit Adapter

The 300 Series Adapter (Inland #40317) enables precision drilling and fine detailing without removing existing ¾" or 1" diamond grinding drums. Designed for seamless integration with Inland grinders, this adapter supports 1/8" (3mm), 1/4" (6mm), and 3/8" (10mm) drilling bits on a 0.312" (7.92mm) arbor with ultra-low TIR (<0.0025"/0.0635mm).

Key Features:

• Multi-Task Efficiency: 100-grit diamond abrasive for versatile drilling, grinding, and edge finishing.

• Swiss-Machined Brass Core: Ensures <0.0025" runout for precision alignment and vibration-free operation.

• No Drum Removal: Mounts directly atop ¾" or 1" diamond drums, saving setup time.

Technical Specifications:

• Diameter: 5/8" (16mm)

• Height: 10mm

• Compatibility: Fits Inland, Glastar, and most grinders with 0.312" arbors.

Applications:

• Jewelry Making: Drill precise holes for gemstone settings or micro-engraving.

• Glass & Ceramics: Create clean openings in stained glass or technical ceramics.

• Model Engineering: Detail work on miniature components.

Advantages Over Conventional Adapters:

• True-Spin Guarantee: Pre-diamond application calibration ensures balanced rotation.

• Durability: Brass construction resists wear in high-RPM workflows.

• Cost Savings: Eliminates frequent drum changes, reducing downtime.

Note: Hyperlinks align with precision drilling, lapidary, and industrial grinding workflows, supporting artisans and engineers in achieving rapid, repeatable results.
