Drill bit Irwin 10502010 — Twist drill bit Ø 1.4 cm, 1 pc

Irwin 10502010 is a single twist drill bit with a 1.4 cm diameter supplied as one piece for standard chucks. Designed for general-purpose drilling, this twist drill bit fits a wide range of drills and is intended for precision hole-making, repair tasks and workshop or construction use. The bit combines Irwin’s twist-drill design with the Speedhammer – Plus concept of fast masonry drilling for materials such as brick, block, masonry, concrete and granite when used with compatible machines and appropriate drilling modes.

Advantages

The drill bit offers a combination of fast penetration and efficient dust removal attributed to the patented single-flute Speedhammer design and extra-short drill head, which concentrates cutting forces at the head and reduces clogging. This construction delivers lower vibration during drilling and improved waste evacuation, helping maintain drilling speed and extend service life under typical workshop or on-site conditions. Supplied as a single piece, it is ready for immediate use in standard chucks.

Suitable for

• Drilling through brick and block
• Masonry and concrete drilling tasks
• Granite drilling where compatible with tool and mode
• Precision repair and installation holes in construction and workshop environments

Key specifications

• Diameter: 1.4 cm
• Quantity: 1 piece
• Type: twist drill bit with single flute (Speedhammer – Plus concept)
• Suitable materials: brick, block, masonry, concrete, granite (when used with compatible drill/mode)

How to use

Secure the Irwin 10502010 twist drill bit in a compatible standard chuck and set the drill to the appropriate mode for the target material (rotary or hammer-rotary as supported by the tool and material). Begin drilling at low speed to establish a starting point, then increase speed and apply steady, controlled pressure. Allow the single-flute design to clear dust through the flute; avoid excessive force that can cause overheating or wear. Withdraw the bit periodically for inspection and dust removal during prolonged drilling.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, gloves and dust extraction or a mask when drilling masonry materials. Match drill mode and speed to the material: rotary-hammer mode for concrete and masonry if the tool supports it, rotary for softer blocks when recommended. Store the bit in a dry place to prevent damage.
