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 Intermediate Taps

• Intermediate Taps have a lead of four threads and are used in most general-purpose applications to cut a thread true to a pre-drilled pilot hole.
• Manufactured from HSS this general-purpose tap is designed for use in medium tensile materials and is for hand or general machine use.

About Drill Bit Surface Treatment

• Bright Finish Jobber Drills have no surface treatment and are supplied in the as-ground condition.
• These tools are suitable for general purpose use, particularly for non-ferrous applications.
