Value Collection MSC-04465134 Straight Flute Tap 9/16-12

Product Description

The VALUE COLLECTION MSC-04465134 is a bottoming straight flute tap designed for cutting right-hand internal threads in through-holes and blind holes where full thread depth close to the bottom is required. Manufactured from high-speed steel with a bright/uncoated finish, it cuts 9/16-12 UNC threads with a 4-flute geometry that channels chips efficiently and supports stable cutting in a range of ferrous and non-ferrous materials. The H2 thread limit provides a controlled tolerance class suited to standard fit applications. Thread length is 1-21/32 inches with an overall length of 3-5/8 inches.

This tap is suited to machine shop, maintenance, and fabrication environments where bottoming thread depth is required in blind holes. The bottoming chamfer — typically 1 to 2 thread leads — allows threading to within a few threads of the hole bottom, making it the correct choice when a plug or taper tap cannot achieve the required thread depth. It is commonly used in manual tapping operations with a tap wrench or in CNC and drill-press setups with appropriate tapping attachments.

Key Features

• Bottoming chamfer for threading close to the bottom of blind holes
• 9/16-12 UNC right-hand thread form for standard inch-series fastener applications
• 4-flute straight design supports chip evacuation in a range of workpiece materials
• High-speed steel construction provides wear resistance and toughness during hand and machine tapping
• H2 thread limit for controlled tolerance and standard thread fit
• Bright/uncoated finish — no coating buildup to affect thread tolerance

Compatibility

Designed as a standard bottoming tap for use in any application requiring a 9/16-12 UNC right-hand internal thread. Compatible with standard tap holders, T-handle tap wrenches, and tapping heads sized for the tap shank.

Installation Notes

This tap is installed by a machinist or maintenance technician using a tap wrench, tapping fixture, or CNC tapping attachment. Always ensure the pilot hole is drilled to the correct 9/16-12 UNC tap drill diameter before threading. Use appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. When tapping blind holes, advance the tap carefully and back off regularly to break chips and prevent tap breakage.
