Product Description

Self-Centering Hinge Drill Bit Set for Door and Window Installation

This drill bit set is designed for opening screw holes in door and window hinges. The self-centering drill sleeve ensures precise positioning without displacement, improving drilling accuracy and efficiency.

Materials

Constructed with a brass shell and high-speed steel drill core with external plating.

Available Sizes and Screw Compatibility

Seven product specifications are available: 5/64'', 7/64'', 9/64'', 11/64'', 5mm, 13/64'', and 1/4''. The 5/64'' size creates holes approximately 2mm in diameter for self-tapping screws around 2.2–2.8mm. The 7/64'' size produces approximately 2.8mm holes for 3–3.5mm screws. The 9/64'' size drills approximately 3.5mm holes for 4–4.5mm screws. The 11/64'' size creates approximately 4.5mm holes for 5–5.5mm screws. The 5mm size produces 5mm holes for 5.5–6mm screws. The 13/64'' size creates approximately 5.2mm holes for 6–6.5mm screws. The 1/4'' size drills approximately 6.35mm holes for 7–7.5mm screws.

Features

The drill sleeve fixes the position to ensure drilling accuracy. Wood chips are automatically discharged from holes on both sides of the drill bit top, preventing the bit from becoming stuck.

Usage Guidance

Adjust size selection according to wood hardness: choose smaller sizes for soft wood and corresponding or larger sizes for hard wood.

Variants

Available in 4-piece and 7-piece sets. Both variants measure 18 × 23 × 4 cm. The 4-piece set weighs 120 g, and the 7-piece set weighs 265 g.
