The KENNAMETAL 4149742 is a taper length drill bit designed for precision hole-making in metal fabrication, machining, and industrial drilling applications. Taper length geometry provides greater reach than jobber-length drills while maintaining rigidity for accurate, clean bores. This bit is sold individually and is suited for use in drill presses, milling machines, and CNC machining centers. Licensed machinists and tool-and-die professionals typically select taper length drills when standard-length tools lack the reach needed for deeper hole depths without sacrificing straightness or finish quality.
This drill bit is appropriate for industrial and manufacturing environments where extended reach and hole accuracy are required. It fits standard taper-shank toolholders and is a common selection in job shops, production machining facilities, and maintenance departments handling deep-hole drilling tasks in ferrous and non-ferrous materials.
Designed as an OEM-style replacement or direct-use taper length drill bit for standard taper-shank toolholding systems in industrial machining equipment.
Installation should be performed by a qualified machinist or tooling technician familiar with taper-shank tool mounting procedures. Ensure the machine spindle is fully powered down and locked out before mounting or removing the drill bit. Seat the taper shank fully into the spindle or holder and verify there is no runout before commencing drilling operations. Follow applicable workplace safety and machine tool codes for drill bit handling and speed-feed selection.
