About HSS Straight Flute Short Machine and Hand Taps

• These general-purpose taps are ideal for creating new threads in a wide variety of materials.
• Goliath HSS taps provide a high hardness to toughness ratio, compressive and tensile strength, good abrasion resistance, and resistance to micro-chipping, ensuring a long tool life.

About Metric Coarse

• The angle of the thread is 60 degrees.
• The crest is flat and the thread has clearance at the root allowing the external thread and internal thread to engage well.
• A larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength.
• The major diameter of external thread and pitch is specified by a simple numerical value (most commonly measured in millimeters).

About Taper Taps

• Taper Taps have a lead of eight threads and are used as a starting tap in difficult or high-precision holes.
• Manufactured from HSS this general-purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
