Center Drill - Kent-Moore

The Kent-Moore J-381885 Center Drill is a precision tool engineered for professional technicians requiring accurate pilot and center holes. Designed for demanding automotive and industrial applications, this center drill ensures precise hole initiation, reduces bit wander, and maintains critical alignment for subsequent machining operations.

Key Features

• Precision-Ground Carbide Tip: Delivers superior accuracy for pilot and center drilling across both ferrous and non-ferrous metals.
• Durable Construction: Built to withstand rigorous use in professional service bays and machine shops, ensuring consistent, long-term performance.
• Enhanced Hole Alignment: Promotes concentricity and precise alignment, which is essential for subsequent drilling, tapping, or turning operations.
• Minimizes Bit Wander: Reduces the walking of larger drill bits on various flat and curved surfaces, facilitating clean and accurate hole starts.
• Broad Material Compatibility: Effectively initiates holes in hardened and alloy steels, alongside other common metals, plastics, and wood found in engine, drivetrain, and chassis components.

Applications

This center drill is vital for establishing accurate starting points, a practice that reduces bit deflection and extends the lifespan of larger drill bits. In automotive repair, the J-381885 is invaluable for tasks requiring precise hole placement, such as preparing bores for fasteners, dowel pins, or alignment pins in engine blocks, transmission housings, brackets, and suspension components. For industrial machine shops and fabrication, it consistently prepares workpieces for turning, boring, or tapping operations, ensuring repeatable hole location and alignment across production runs or repair tasks.
