Titan Usa CD40926 Jobber Drill Bit Letter Y Hss

Product Description

The TITAN USA CD40926 is a Letter Y jobber-length drill bit machined from high speed steel with a bright uncoated finish. It features a standard 118-degree split-free point and a regular spiral flute geometry designed for consistent chip evacuation during through-hole and blind-hole drilling operations. The straight cylindrical shank measures 0.4130 inches in diameter and seats directly into standard drill chucks without adapters. At 5.25 inches overall length with a 3.875-inch flute, this bit delivers a 9xD depth-to-diameter ratio suited to general-purpose production and maintenance drilling tasks. It is installed and used by machinists, millwrights, maintenance technicians, and tool-room operators.

The CD40926 is designed for drilling non-ferrous metals including aluminum, brass, copper, and similar soft alloys where a bright uncoated surface reduces built-up edge and promotes clean hole finish. The 2-flute right-hand spiral configuration handles both hand-held drill work and machine spindle applications such as drill presses, lathes, and CNC machining centers. The 1.375-inch shank length provides adequate chuck engagement across standard keyless and keyed chucks. Typical applications include fabrication shops, HVAC equipment assembly, plumbing rough-in metal work, and electrical panel shop work where Letter Y clearance or tap-drill sizing is required.

Key Features

• Letter Y sizing at 0.4130 inches diameter with a tight tolerance of -0.0010 to +0.0000 inches for accurate hole sizing
• 118-degree standard point angle for self-starting entry on non-ferrous and soft materials
• High speed steel construction provides adequate hardness and heat resistance for general-purpose drilling
• Bright uncoated finish reduces friction and material adhesion when drilling aluminum and non-ferrous alloys
• Regular spiral 2-flute design promotes efficient chip clearance at a 9xD flute-to-diameter ratio
• Straight cylindrical shank fits standard drill chucks without any adapter required

Compatibility

Designed as an OEM-style jobber drill replacement compatible with standard 3-jaw keyed and keyless drill chucks accepting a 0.4130-inch straight cylindrical shank, suitable for use in hand drills, drill presses, lathes, and CNC machining centers.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the shank fully within the chuck jaws and verify runout before beginning a drilling cycle. Always power down and de-energize the machine spindle before changing bits or clearing chips. Do not exceed the recommended feed and speed ranges for the workpiece material and bit diameter as excessive heat will reduce tool life on uncoated HSS tooling.
