Wera Phillips insert bits are suitable for both hand and power driven bit holders. With many styles to choose from there's literally a bit for every material and screw driving situation.

851/1 Diamond Coated Impaktor bits

Wera Impaktor Bits were specifically designed to withstand high power tool impact forces.  The Diamond coated tips grip the fastener and reduce the pressure required for fastenting. 

851/1 BDC Bits (BiTorsion Dimaond Coated Bits) 

Wera BiTorsion bits prevent premature wear caused from peak forces that occur in power tool applicatons and prevent damage to the screw head.  Wera BiTorsion bits have a cushioning torsion zone that diverts kinetic energy away from the ti during peak loads.  The Diamond coated tips ensure a secure fit into the screw head and reduce the chances of cam-out.

851/1 BTH Bits (BiTorsion H Bits)

Wera BiTorsion bits prevent premature wear caused from peak forces that occur in power tool applicatons and prevent damage to the screw head.  Wera BiTorsion bits have a cushioning torsion zone that diverts kinetic energy away from the ti during peak loads.  Wera H Bits are extra hard bits for semi-hard materials like wood.

851/1 BTZ Bits (BiTorsion Z Bits)

Wera BiTorsion bits prevent premature wear caused from peak forces that occur in power tool applicatons and prevent damage to the screw head.  Wera BiTorsion bits have a cushioning torsion zone that diverts kinetic energy away from the tip during peak loads.  Wera Z Bits are designed for hard materials like sheet steel or metal.

851/1 A Bits (Aviation Bits)

851/1 ADC Bits  (Diamond Coated Aviaton Bits)

Wera ADC Bits are Aviation bits with a Diamond Coating on the tip.  The Diamond coated tips grip the screw, ensuring a secure fit into the screw head and reducing the chances of cam-out.

851/1 AH Bits (Wera Aviation Bits designed for Semi-Hard Materials)

These Wera AH bits are part of Wera's line of Aviation bits, but are extra hard bits designed for semi-hard materials like wood.

851/1 J Bits (Japanese Bits- for use with standard screws used in Japanese Cameras)

851/1 RDC Bits (Diamond Coated Bits for Drywall Screws) 

Wera RDC Bits are Diamond coated bits designed for securely fastening Drywall Screws.  The Diamond coated tips ensure a secure fit into the screw head and reduce the chances of cam-out.

851/1 RH Bits (Extra-hard bits for Drywall screws)

Wera RH bits are a part of Wera's H series bits designed specifically for Dry Wall Screws.  Wera's H Bits are extra hard for fastening in Semi-Hard Materials. 

851/1 RZ Bits (tough Bits for Drywall Screws)

Wera RZ Bits are a part of Wera's Z series Bits specifically designed for Drywall Screws.  Wera Z Bits are Extra tough for fastening in hard materials.  Wera Z bits are designed to handle high torque peaks generated when the screw head touches the material and prevent premature breakage.

851/1 TH Bits (Extra-Hard torsion Bits for semi-hard material)

Wera TH Bits are a part of Wera's H series bits with a Torsion zone.  The Torsion bits absorb the damaging peak torque loads in the torsion zone, preventing premature wear.  The extra-hard bits are ideal for fastening in semi-hard material like wood.

851/1 TiN Bits (Titanium-Nitride Bits)

TiN Bits are Titanium-Nitride bits.  They have an extremely hard coating to withstand permanent loads such as during continual screwdriving operations in series manufacturing.

851/1 Z bits (Extra Tough Bits for hard materials)

Tough Bits for hard materials like sheet steel or metal.  Wera Z bits are designed to handle high torque peaks generated when the screw head touches the material and prevent premature breakage.

851/1 TZ Bits  (Extra Tough Torsion Bits)

Wera TZ Bits are ductile, tough bits with a Torsion Zone.    The Torsion bits absorb the damaging peak torque loads in the torsion zone, preventing premature wear.  They are ideal for fastening in hard materials like sheet steel or metal.

853/1 TZ bits ACR (Extra Tough Torsion Bits with Anti cam-Out Ribs)

For use with hard materials such as sheet metal. Torsion zone reduces initial impact, increasing service life of the tip.  The ACR Bits are designed with Anti Cam-Out Ribs which prevents the bit from slipping out of the screw head.
