Drill Bit Set c.k tools T3112 — Spiral 5-piece, hex shank

Spiral Drill Set c.k tools T3112 — Spiral 5-piece, hex shank is a compact kit of five spiral twist drill bits with hexagonal shanks designed for rapid bit changes and secure retention in hex chucks or bit holders. The set is intended for use with power drivers and impact drivers that accept hex shank bits and is suitable for a range of general drilling operations in compatible materials. The design combines straightforward geometry with convenient shank form to increase usability on-site and in the workshop.

Advantages

The hex shank design ensures a positive fit in standard bit holders and quick-change chucks, reducing slippage during high-torque use. Spiral flutes provide efficient chip evacuation and stable cutting action for general-purpose drilling. The five-piece configuration gives a compact selection of commonly used sizes, allowing faster job setup and fewer tool changes. The compact storage arrangement keeps the bits organized and protected when not in use.

Подходит для

• Общих сверлильных работ по дереву и мягким пластикам
• Монтажных и ремонтных задач на объектах и в мастерской
• Использования с шуруповёртами и ударными драйверами, принимающими шестигранные хвостовики
• Быстрой смены насадок при серийной сборке и установке

Key specifications

• Shank type: 1/4-inch hex shank for quick-change chucks and bit holders
• Flute form: spiral (twist) for chip evacuation and cutting stability
• Intended drive compatibility: power drivers and impact drivers accepting hex shank bits
• Use case: general-purpose drilling in compatible materials such as timber and soft plastics
• Storage: compact holder for organized transport and storage

How to use

Select the appropriate drill bit size from the five-piece set for the material and hole diameter required. Insert the hex shank fully into the driver’s chuck or bit holder until it seats firmly. Secure the driver or chuck according to the tool manufacturer’s instructions. Begin drilling at low speed to establish the hole, then increase speed and apply steady, even pressure suitable for the material. Retract periodically to clear chips when drilling deeper holes. After use, allow any heated bits to cool, then return them to the compact holder for storage.

Usage recommendations

Use the spiral drill bits with appropriate cutting speeds and feed rates for the target material. Avoid excessive side load and lateral bending. For harder materials, select a purpose-made drill bit type. Regularly inspect the flutes and cutting edges for wear and replace bits that are blunt or damaged to maintain performance and reduce risk of breakage.
