Detailed Reviews

What to Look For Drill Bits Uk Reddit

Tool Material

The core alloy (e.g., M35 cobalt‑enriched HSS) determines wear resistance, heat tolerance, and longevity, especially when drilling hard metals like stainless steel.

Diameter Range

The smallest to largest bore size (e.g., 1.5 mm‑6.5 mm) dictates which holes can be made and influences precision for fine‑detail versus larger‑diameter work.

Shank Type

Straight, hex, or SDS shanks affect compatibility with drills, chuck grip security, and vibration reduction, influencing accuracy and ease of bit changes.

Coating/Finish

Surface treatments such as TiN, TiAlN, or black oxide improve hardness, reduce friction, and extend bit life, especially under high‑speed or high‑temperature conditions.

Maximum RPM Rating

The highest safe rotational speed (e.g., 10 000 rpm) ensures the bit can be used with powerful cordless or bench drills without overheating or failure.

Overall Length

Total length (including shank) determines reach into deep or confined spaces and affects leverage, impacting stability and control during drilling.

Buying Guide

Key Features to Consider

When selecting drill bits for UK projects, focus on material composition, geometry, and coating. High‑speed steel (HSS) offers versatility for wood and metal, while cobalt or carbide tips excel on hardened steel. Look for a split‑point or brad point design to reduce walking and improve accuracy. Coatings such as TiN, TiAlN or black oxide extend life by reducing friction and heat buildup.

Budget Recommendations

For casual DIYers, a mixed‑size HSS set from £15‑£30 provides adequate performance across wood, plastic and soft metals. Enthusiasts seeking longer durability should aim for a cobalt‑based kit in the £35‑£55 range, which handles stainless steel and tougher alloys. Professional users will benefit from premium carbide or titanium‑coated sets priced between £70 and £120, delivering superior wear resistance and consistent cutting speeds.

Common Pitfalls to Avoid

Avoid buying generic, unbranded bits that lack proper heat‑treated cores; they dull quickly and can damage workpieces. Don’t rely on a single size for all tasks—using the wrong diameter increases wobble and torque strain. Finally, neglecting proper storage, such as leaving bits loose in a toolbox, leads to edge chipping; invest in a magnetic or compartmentalised holder to preserve sharpness.

Frequently Asked Questions

What are the most recommended drill bit brands on UK Reddit threads?

Redditors in UK DIY and woodworking subreddits frequently praise brands like Bosch, DeWalt, Makita, and the more budget‑friendly Draper. For high‑precision work, many users recommend the Irwin (formerly Black & Decker) and the Japanese‑made Dremel bits for small projects.

Do UK Reddit users prefer cobalt or titanium‑coated bits for metal drilling?

The consensus is that cobalt bits are favored for drilling hard metals (e.g., stainless steel) because they retain hardness at higher temperatures. Titanium‑coated bits are popular for occasional metal work and for wood or plastic, but Redditors note the coating can wear off quickly with heavy metal use.

Is it worth buying a set of HSS (High Speed Steel) bits or should I go straight to carbide?

Most UK Reddit contributors suggest starting with a good quality HSS set for general purpose drilling—it's versatile and cost‑effective. Carbide bits are reserved for very hard materials (concrete, masonry) or high‑volume professional work, as they are more brittle and expensive.

What drill bit sizes are essential for typical UK DIY projects?

A practical starter set, as recommended on r/DIYUK, includes: 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 13 mm, and 16 mm HSS bits for wood and metal, plus a 6 mm and 8 mm masonry bit if you need to drill into brick or concrete.

How do I maintain drill bits to keep them performing like they do in Reddit’s “best drill bits” lists?

Reddit users stress regular cleaning, proper storage, and occasional sharpening. After each use, wipe bits clean of dust and oil, store them in a dry, padded case, and use a bench grinder or a dedicated bit sharpener when the cutting edge becomes dull. For coated bits, avoid grinding the coating away; instead, replace them when wear is noticeable.
