MAKITA D-60137 HSS-G Black Oxide Metal Drill Bit 13/32" x 5-1/4"

MAKITA D-60137 HSS-G Black Oxide Metal Drill Bit, Size 13/32x5-1/4 inch
Specifications The D-60137 drill bit belongs to Makita's Imperial HSS-G Black Oxide range, designed for high performance and durability in medium to heavy-duty metal drilling applications.Material & Manufacturing (HSS-G): Made from premium High-Speed Steel (HSS), fully ground along the flutes for a sharp, uniform cutting edge, which is essential for larger diameter bits to maintain balance and drilling accuracy.Surface Coating (Black Oxide): The black oxide finish provides excellent resistance against rust and corrosion. It also acts as a dry lubricant, reducing friction and heat buildup during drilling to extend tool life.Tip Design (Split Point): The 135° split point tip is the standard for high-performance metal drilling, allowing the bit to bite into the material immediately without slipping or walking, which is critical for larger diameter bits.                                                                                                                                                                Features
135° Split Point Tip: Delivers maximum starting accuracy, minimizing wandering and eliminating the need for a center punch even on larger diameter holes.
Fully Ground Construction (HSS-G): Ground flutes provide a consistent cutting edge and flawless geometry, ensuring rapid chip evacuation and reduced jamming.
Black Oxide Durability: Black oxide coating prevents rust and significantly increases resistance to heat and friction.
High Balance: Ideal for use with drill presses or large handheld power drills where high accuracy is required.
