Eagle Cutting Tool MT-035-060-B-I M3.5x0.60 Hss Bottom Tap

Product Description

The EAGLE CUTTING TOOL MT-035-060-B-I is an M3.5 x 0.60 mm pitch high-speed steel (HSS) bottom tap designed to cut full threads to the bottom of a blind hole. This metric tap produces a 3.5 mm thread with a 0.60 mm pitch and is ground from HSS for durability across a range of workpiece materials. Bottom taps carry minimal lead chamfer, typically one to two threads, allowing the cutting teeth to reach the floor of a blind bore where plug or taper taps cannot complete the thread. It is used by machinists, pipefitters, tool-and-die technicians, and maintenance tradespeople performing metric threading operations on ferrous and non-ferrous materials.

This tap is suited for production and maintenance threading tasks where a complete thread depth is required in a blind hole. Typical applications include machine repair, fixture fabrication, and component assembly work involving M3.5 metric fastener sizing. The 0.60 mm pitch corresponds to the standard coarse pitch for M3.5 threads, making this tap compatible with standard M3.5 metric fastener specifications. At 0.09 pounds, the tap is lightweight and sized for use in hand tap wrenches or low-speed machine tapping setups.

Key Features

• M3.5 x 0.60 mm pitch metric thread form for standard coarse M3.5 fastener compatibility
• Bottom tap geometry with minimal lead chamfer to thread blind holes to full depth
• High-speed steel (HSS) construction for hardness and wear resistance across common workpiece materials
• Lightweight at 0.09 pounds, suitable for hand or low-speed machine tapping
• Minimum order quantity of 1, available as a single unit

Compatibility

Designed as a standard M3.5 x 0.60 mm coarse-pitch metric bottom tap for use wherever M3.5 metric threads must be cut to the bottom of a blind hole.

Installation Notes

Bottom taps should always be used as the final tap in a sequence after a taper or plug tap has established the thread lead in the hole. Power down and secure all equipment before manual tap changes in machine setups. Use appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Broken tap removal is difficult in small-diameter taps, so avoid excessive torque and back off frequently to clear chips.
