Spiral Taps（Screw size (Nominal)：7/8）
[What is a spiral tap?]
A cutting tap with grooves twisted so as to discharge chips in the direction opposite to the tap traveling direction (front side), making it ideal for machining "blind hole" threads. As it has good machinability, it is suitable for viscous materials (stainless steel, aluminum, copper, etc.). Also, as the discharge of chips is good, it is also suitable for machining. There are two types of materials, mainly HSS (= high speed steel) and carbide: HSS is tough and hard to break and carbide is abrasion resistant.

Spiral Fluted Taps for Stainless Steels_SU+SP
YAMAWA MFG
Spiral tap for blind hole machining with extremely viscous or work-hardened work material.
[Features]
· For blind hole machining with extremely viscous or work-hardened work materials such as chrome steel, molybdenum steel, and stainless steel.
· Optimal design of the screw part reduces the machining burden on each blade bite, reducing the cutting resistance and increasing tool life.
· Stable scrap is ejected and a good finish is realized.
· Capable of machining both synchronously and asynchronously.
· Machining speed of 10 m/min or less is recommended.
[Applications]
Optimal for machining extremely viscous or work-hardened work material.Screw size (Nominal) Screw Types work material Pitch (P), Number of Threading(mm) Tool Material Type Tap Type Hole type Chamfer threads (Lcf) Coating Type Coating Y/N Overall Length (L)(mm) 7/8 unified / Whitworth High Carbon Steel (C with a content over 0.45%)[○] / Alloy Steel (SCM)[○] / Stainless steel (SUS)[○] 9 ～ 14 High-speed steel Spiral Tap For blind hole 2.5P - NA 115 From: ₹ 11,955.40 Days to Ship: 7 Day(s) or more
