Drill bit Irwin 10501992 twist drill bit, diameter 1.2 cm, 1 pc

Irwin 10501992 is a single twist drill bit with a diameter of 1.2 cm supplied as one piece for general-purpose drilling. The solid twist geometry and single-flute design enable efficient removal of debris during drilling. The bit fits standard drill chucks and is suitable for use in hand-held and machine drilling operations; its construction is intended to provide reliable performance when working with a range of common materials depending on the machine and operating conditions.

Advantages

The twist geometry and single flute promote faster dust evacuation and reduce vibration compared with conventional straight-flute bits, improving drilling progress. The compact head is engineered to take the majority of the cutting load, which helps maintain drilling speed and reduces the risk of clogging by channeling dust directly into the flute. Supplied as a single unit, the bit is ready to install in compatible chucks and is designed for straightforward replacement.

Suitable for

• Drilling holes in concrete and masonry
• Drilling in brick and block materials
• General-purpose drilling in wood, metal or plastic depending on drill and settings
• Hand-held and machine drilling applications

Key specifications

How to use

Secure the drill bit in a compatible chuck or SDS-plus holder according to the drill manufacturer’s instructions. Select an appropriate drilling speed and apply steady, even pressure while keeping the drill perpendicular to the work surface. For masonry and concrete, use hammer-drill or rotary-hammer functions as required by the material and the drill. Withdraw the bit periodically to clear accumulated dust and allow the flute to evacuate debris.

Usage recommendations

Use appropriate personal protective equipment including eye protection and hearing protection when drilling. Match drill speed and hammer action to the material; for hard masonry and concrete, use hammer mode and moderate feed pressure. Inspect the bit regularly for wear and replace it when cutting performance decreases or the head is damaged.
