Twist drill bit Cimco 208341

The Cimco 208341 twist drill bit is a single-piece rotary hammer accessory designed for right-hand rotation. With a nominal working diameter of 1.2 cm and a total length of approximately 26 cm with a 20 cm working length, this drill bit is made for drilling tasks that require straight, reliable holes. Its robust construction supports repeated use in common building materials, offering consistent penetration and stable performance when paired with an appropriate rotary hammer.

Advantages

The drill bit combines a solid single-piece design and a geometry suited to rotary hammer operation, which promotes durability and straight drilling. Its specified diameter and working length provide a balance between reach and stiffness, reducing flex during use. Right-hand rotation compatibility makes it suitable for standard rotary hammers and ensures conventional drilling direction and chip evacuation. The construction is intended to withstand the impact and torque typical of rotary hammer applications.

Suitable for

• Drilling holes in masonry and concrete with a compatible rotary hammer
• Installation of anchors, plugs or through-holes in construction tasks
• Professional and DIY jobs where a 12 mm diameter hole is required

When it may not be suitable

This twist drill bit is designed specifically for rotary hammer use and may not perform correctly in standard hand drills or drill drivers that do not support hammer action or the required chuck/shank interface. It is not intended for precision metal drilling or delicate finishing tasks where a specialized metal or wood bit would be required. Use in materials outside typical masonry or concrete may reduce life span and effectiveness.

Key specifications

• Intended tool type: rotary hammer
• Rotation direction: right-hand
• Nominal diameter: 12 mm
• Total length: approx. 26 cm
• Working length: approx. 20 cm
• Sold as: single piece

How to use

Select a compatible rotary hammer and secure it according to the tool manufacturer’s instructions. Fit the drill bit fully into the chuck or SDS holder and ensure it is locked. Mark the drilling point, start at low speed to establish position, then apply steady pressure while engaging hammer action as required for masonry. Withdraw the bit occasionally to clear debris and prevent overheating. After use, clean and store the bit in a dry place to prevent corrosion and maintain cutting performance.

What to consider before purchase

• Confirm your rotary hammer accepts the bit’s shank type and supports right-hand rotation
• Ensure 12 mm diameter and ~20 cm working length meet the hole size and depth requirements
• Check that the intended material (masonry or concrete) is suitable for this type of bit

Usage recommendations

Use personal protective equipment such as safety glasses and hearing protection, and follow the rotary hammer manufacturer's speed, pressure, and hammering recommendations. For best results in reinforced concrete, reduce feed pressure and use intermittent drilling to extend bit life.
