Drill Bit Fischer 545507 1.2 cm Diameter 1 pc

The Fischer 545507 drill bit is a single-piece spiral bit with a 1.2 cm (12 mm) diameter designed for general drilling tasks. Intended for use with compatible drills, this bit is manufactured for accurate hole-making and consistent performance across common construction and renovation materials. The design emphasizes straightforward use and wear resistance suited to frequent drilling operations.

Advantages

This Fischer drill bit offers a uniform 12 mm diameter for predictable hole size and fit. The spiral flute design evacuates debris efficiently during drilling to help maintain cutting performance. Built from hardened tool steel and finished for durability, the bit is intended to provide a balance of precision and longevity in standard drilling applications.

Suitable for

• Drilling holes in masonry, concrete and stone where a spiral masonry bit is appropriate
• General construction and renovation tasks requiring a 12 mm hole
• Anchoring and fixing installations that need a consistent hole diameter

When it may not be suitable

This drill bit may not be optimal for high-speed steel drilling of soft metals or for precision metalwork where specialised metal or carbide bits are required. It is not a multi-piece set; only a single 12 mm bit is supplied, so users needing multiple sizes or replacements should consider a set.

Key specifications

• Diameter: 12 mm
• Quantity: 1 piece
• Tip and flute: spiral masonry-style design for debris removal
• Intended materials: masonry, concrete and stone
• Compatibility: for use with hammer drills and rotary drills that accept the bit shank

How to use

Select a drill with a suitable chuck and secure the Fischer 12 mm bit tightly. Mark the drilling point and start at low speed to position the tip, then apply steady pressure while increasing speed suitable for the material. For masonry and concrete, use hammer mode if available and clear dust periodically to avoid clogging. After drilling, withdraw the bit while the drill is running slowly to remove residual dust from the hole.

What to consider before purchase

• Confirm that a single 12 mm drill bit meets your project needs or if a multi-size set is more appropriate
• Check that your drill supports the required bit shank size and hammer mode if drilling masonry
• Consider material compatibility — this bit is optimized for masonry, concrete and stone rather than for metal or wood specialized work

Usage recommendations

Use protective equipment, operate the drill at appropriate speeds, and let the bit cool periodically when performing extended drilling tasks. Store the bit in a dry place to prevent corrosion and inspect the tip before use to ensure effective performance and consistent hole quality.
