Spiral Drill C.K Tools T3035 12mm, Length 151mm

Spiral Drill C.K Tools T3035 12mm, Length 151mm is a long-reach twist drill designed for tasks where extra reach and reliable chip evacuation are required. With a 12 mm cutting diameter and an overall length of 151 mm, this spiral drill is intended for general-purpose drilling in materials such as metal, wood and plastic depending on cutting speed, feed and clamping. The flute geometry promotes consistent chip removal and helps maintain a straight bore when used with appropriate drill speeds and secure workholding.

Advantages

The 151 mm overall length provides extended reach for drilling into recessed or hard-to-access areas while the 12 mm diameter covers a common range of fastening and component hole sizes. Spiral flutes facilitate efficient chip clearance to reduce clogging and overheating. The drill’s geometry is optimised for straight drilling performance under proper operating conditions, and the solid construction supports workshop and maintenance use where durability and repeatable results are required.

Suitable for

• Drilling holes in sheet and plate metal where deeper access is needed
• Recessed or through-holes in wooden assemblies and furniture repair
• Plastic components in maintenance and prototyping where chip control matters
• Workshop and maintenance tasks requiring extended reach from a hand drill or drill press

Key specifications

• Cutting diameter: 12 mm
• Overall length: 151 mm
• Drill type: spiral / twist drill
• Suitable materials: metal, wood, plastic (dependent on cutting conditions)
• Flute design: spiral flutes for chip evacuation

How to use

Select an appropriate cutting speed and feed rate for the material being drilled; slower speeds and steady feeds are typical for harder metals while higher speeds suit softer materials like wood and some plastics. Secure the workpiece with clamps or a vice to prevent movement. Install the drill in a compatible chuck and ensure it is centred and tightened. Use cutting fluid when drilling metals to improve tool life and chip evacuation. Apply steady pressure, avoid excessive side loads and withdraw periodically for deep holes to clear chips.

Usage recommendations

For best results, start with a pilot hole for precise location when accuracy matters, and ensure the drill is run at the recommended speeds for the specific material. Regularly inspect the cutting edges for wear and replace the drill when performance degrades.
