MAKITA D-60121 HSS-G Black Oxide Metal Drill Bit 25/64" x 5-1/8"

MAKITA D-60121 HSS-G Black Oxide Metal Drill Bit 25/64 x 5-1/8 in.
Features: The D-60121 drill bit is part of Makita's Imperial HSS-G Black Oxide series, designed for professional metal drilling requiring high precision and long service life. HSS-G Construction: Manufactured from high-quality High-Speed Steel (HSS) with a fully ground flute along its entire length for a sharp cutting edge and perfectly symmetrical geometry, providing high drilling stability and precision, especially for larger drill bit sizes. Black Oxide Coating: The black oxide surface treatment provides rust resistance and acts as a dry lubricant to reduce friction between the bit and the workpiece, lowering heat buildup and extending tool life. 135° Split Point: The 135-degree split point tip enables self-centering and immediate bite into the workpiece without excessive feed force, preventing walking and making 25/64-inch (9.92 mm) hole drilling fast and precise.
Features
High precision with 135° Split Point: Enables easy starting and precision drilling in hard metals without center punching. Fully ground HSS-G: Delivers superior cutting sharpness and highly efficient chip extraction to reduce bit jamming. Enhanced durability with Black Oxide: Black oxide finish effectively reduces heat and friction, extending bit life when drilling metals. Robust construction: Ideal for use with electric drills or drill presses to drill holes approximately 10 mm in diameter.
Application
The MAKITA D-60121 drill bit is suitable for a wide range of metal drilling applications in industrial, structural, and maintenance work requiring medium-sized holes: Metals: Alloy and non-alloy steel, cast iron, mild steel, non-ferrous metals such as aluminum and brass. Structural work: Suitable for drilling fixing holes or pilot holes in various metal structures. General materials: Efficiently drills thick wood or hard plastics.
