Achieve professional-grade precision with our Universal Drill and Counterbore Jig Kit, specifically designed for 2020, 3030, and 4040 T-Slot Aluminum Profiles. This jig is an essential tool for builders who need to create clean, recessed bolt holes for hidden fasteners and internal connections without the need for a drill press.

Constructed for high repeatability, this jig ensures your holes are perfectly centered every time, preventing "walking" on the curved surfaces of the extrusion. This kit allows you to create the necessary clearance for socket head cap screws to sit flush or below the profile surface, ensuring a sleek, professional finish for sim rigs, CNC machines, and industrial framing.

Note: This kit includes the jig guides and alignment hardware. Drill bits are not included.

Key Features:

• Multi-Series Compatibility: Works seamlessly with 20mm, 30mm, and 40mm profiles.
• Precision Alignment: Locks securely into the T-slot channel to guarantee perfectly centered holes.
• Professional Finish: Enables clean counterboring for recessed fasteners and "hidden" joints.
• Hardened Durability: Designed for high-frequency use with aluminum and alloy extrusions.
• Universal Tooling: Compatible with standard hand drills and most woodworking/metalworking bits.
