Value Collection MSC-04477121 Straight Flute Tap 3/4-10

Product Description

The VALUE COLLECTION MSC-04477121 is a straight flute tap designed to cut internal 3/4-10 UNC right-hand threads in a wide range of workpiece materials. Built from high-speed steel with a bright, uncoated finish, this taper chamfer tap provides the gradual thread engagement needed to start threads accurately in through-holes or when maximum chip clearance is required. The 4-flute geometry delivers solid thread form and rigidity during the cutting cycle. With a 2-inch thread length and a 4-1/4-inch overall length, the tool fits standard tap handles and machine spindles used in production and maintenance machining environments. Machinists, toolmakers, and maintenance technicians are the primary users.

This tap is suited for threading operations in metalworking shops, maintenance and repair facilities, and light manufacturing environments. Taper chamfer taps are the standard starting choice when threading by hand or initiating the cut in a machine tapping cycle, as the load is distributed across several leading threads. The 3/4-10 UNC thread form is common in structural fastener applications, machinery frames, and heavy equipment assemblies where coarse-thread fasteners are standard. The H3 thread limit designation indicates a controlled tolerance class appropriate for standard UNC fit requirements.

Key Features

• 3/4-10 UNC thread form with right-hand thread direction
• Taper chamfer distributes cutting load across multiple leading threads for easier starting
• High-speed steel construction provides toughness and wear resistance across a broad range of machinable materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• H3 thread limit for consistent tolerance control on standard UNC fits
• 4-flute design promotes thread form accuracy and tool rigidity

Compatibility

Designed as a standard straight flute taper tap for cutting 3/4-10 UNC internal threads in through-hole and open-ended applications where chip evacuation along the flute is adequate.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians using a calibrated tap handle, tapping head, or machine spindle rated for the torque demands of a 3/4-10 tap. Always apply an appropriate cutting fluid for the workpiece material and ensure the tap is aligned perpendicular to the workpiece surface before engagement. Do not force a tap against resistance; back off periodically to break chips and prevent tap breakage. Secure the workpiece firmly before beginning the threading operation.
