OVERVIEW

Precision Threading with Walter High Speed Steel Taps

The Walter 03B061 3/8-16NC Taper HS Tap is an industrial-grade threading tool designed for professionals who demand accuracy and longevity. Crafted from the finest High Speed Steel (HSS), this tap is engineered to withstand the rigors of cutting threads into tough materials, including stainless steel, mild steel, and aluminum. Unlike standard carbon steel taps, Walter's HSS construction maintains its cutting edge longer, resisting heat build-up and wear even during intensive use.

One of the standout features of this tool is its precision ground threads. This manufacturing process ensures that every cut is clean, accurate, and consistent, reducing the torque required to turn the tap and minimizing the risk of breakage. The tap has been meticulously hardened and tempered, striking the perfect balance between hardness for cutting and toughness to resist snapping under load. This makes it an invaluable asset in machine shops and manufacturing environments where downtime due to broken tools is not an option.

The "Taper" style of this tap features a chamfer of approximately 7 to 10 threads. This design is specifically intended to help align the tap with the hole, making it the easiest style to start straight. It distributes the cutting load across more teeth, which is particularly beneficial when tapping tough alloys or when working by hand. Whether you are creating new threads in a through-hole or cleaning up existing ones, the Walter 03B061 delivers the performance and reliability expected from a leader in surface technologies.

Invest in tools that work as hard as you do. The Walter 3/8-16NC Taper Tap provides the confidence needed for critical threading operations, ensuring a perfect fit for fasteners every time.

FAQ

The standard drill bit size for a 3/8"-16 NC tap is 5/16". Using the correct drill size is critical to ensure proper thread percentage and prevent tap breakage.

A taper tap has a long chamfer (7-10 threads) which helps align the tap with the hole. It is best used for starting new threads or for tapping through-holes where the tap can pass completely through the material.

Yes, this tap is made from High Speed Steel (HSS) and is specifically designed to be durable enough to cut threads in stainless steel, as well as mild steel and aluminum.

NC stands for 'National Coarse'. It refers to the thread pitch standard. A 3/8"-16 NC tap creates 16 threads per inch, which is the standard coarse thread for a 3/8" diameter bolt.

Yes, using a high-quality cutting oil or tapping fluid is highly recommended. It reduces friction, dissipates heat, and helps clear chips, significantly extending the life of the tap and improving thread quality.

While you can start a blind hole with a taper tap, it cannot thread all the way to the bottom due to its long chamfer. For blind holes, you would typically start with a taper tap and finish with a bottoming tap.

The main difference is the chamfer length. A taper tap has 7-10 tapered threads for easy starting, while a plug tap has 3-5 tapered threads and is used for general purpose threading or bringing threads closer to the bottom of a hole.
