847 HSS Combined tap bit M 8, core hole 6.8 mm, length 51 mm, 1/4" hexagon - Wera 05104644001

An M 8 thread in sheet metal or a profile normally needs a drill, a tap and a deburring tool, meaning three tool changes. The 847 combined tap bit handles core-hole drilling at 6.8 mm, tapping and deburring in one operation directly in a cordless screwdriver.

Benefits

• Drilling, tapping and deburring in one operation saves tool changes.
• Excellent centring properties and low jamming risk for straight threads.
• Perfect chip removal and precise return control when backing out.
• HSS with finely tuned material elasticity for long service life.
• 1/4" hexagon shaft for very good power transfer.

Applications

Metalwork, control cabinet and enclosure construction, assembly and maintenance: producing M 8 threads quickly on site in sheet metal, profiles and thin-walled parts.

Standards and safety

1/4" hexagon drive as per DIN 3126-D 6.3 and ISO 1173.
