Jonnesway 8x75mm 6-point ampoule bit, 10mm D175H80

Jonnesway 8x75mm 6-point ampoule bit with a 10 mm tip diameter, model D175H80, is a replacement ampoule-style screwdriver bit made for use with compatible bit holders, manual screwdrivers and power tools accepting 8x75 mm bits. The bit features a 6-point (hex) profile designed to engage hex-head fasteners precisely, offering a stable connection and controlled torque transfer for general workshop, garage and maintenance tasks.

Advantages

The ampoule-style design concentrates material around the working tip to increase strength and reduce breakage risk under torque. The 6-point hex profile provides full-face contact with hex fasteners, minimizing rounding and slippage compared with lower-contact profiles. At 75 mm length the bit gives extended reach into recessed or hard-to-access fasteners while the 10 mm tip diameter matches common hex-head sizes for reliable engagement. Manufactured to fit standard 8x75 mm bit holders, the bit is compatible with many hand and powered drivers.

Suitable for

• Workshop and garage fastening and loosening of hex-head bolts and screws
• Maintenance and repair tasks on machinery and equipment with 10 mm hex fasteners
• Use with bit holders, impact drivers and manual screwdrivers that accept 8x75 mm bits
• Reaches recessed fasteners in assemblies or panels

Key specifications

• Bit type: ampoule-style (box-end/hex) screwdriver bit
• Profile: 6-point (hex)
• Overall length: 75 mm
• Working tip diameter: 10 mm
• Shank size: 8 mm (designed for 8x75 mm bit holders)
• Compatibility: for use with compatible manual and powered bit drivers

How to use

Insert the 8x75 mm shank securely into the bit holder or chuck of the driver, ensuring it seats fully to prevent wobble. Align the 6-point tip with the hex fastener and apply steady axial pressure while turning the driver to engage the fastener. For power tools, start at low speed to confirm correct alignment and then increase speed as needed. Inspect the bit tip before each use for wear or damage and replace the bit if rounding or chipping is visible to maintain safe and effective operation.

Usage recommendations

Use the bit with the proper torque settings for the fastener size and material; avoid excessive impact or over-torquing which can damage the bit or fastener. Store the bit in a dry place and keep it clean from grease and debris to prolong service life. For high-torque applications prefer impact-rated bits and compatible impact drivers.
