Best spade drill bits

Updated: 2026-10-23

You already know the hole: a hidden cable run, a door lock, or one diameter you will drill this afternoon. Best spade drill bits, on this page, means which of the twelve amazon.co.uk rows fits that hole, and which title you should not trust. It does not mean a single winner for every job. Prices from the 19 October 2026 listings, and the scores, are in the [spade bit comparison](/hub/drilling-and-accessories/spade-bit). Badges there are a score inside this set, not a lab test and not Amazon’s best-seller rank. This page assumes you can already say what the hole is.

What the badges actually are

The top pick is the SHALL eight-piece set at about £10.99, with 4.7 from 1,042 ratings. It ties the Gunpla 13-piece set, and the larger review count takes the badge. Several five-star texts say the bits had not been used. Best value is the Gunpla six-piece set at about £6.98, with 4.5 from 287 ratings, in a blister rather than a pouch. The surface cell says Metal, Wood while the bullets describe board. Reviewers report bent 10 mm points. If you still need a diameter and a timber sentence, use the spade bit buying guide first.

A set for hidden holes and doors

If the holes will be hidden, SHALL is the row the score prefers. The table says wood, not hardwood, and titanium in the finish field is not the carbon-steel line. Drilling 32 mm only because it is the largest bit in the bag is a poor reason. The Gunpla 13-piece set is the wider list, with a pouch. The first sharpness does not last, and the pieces cell says 1. Count the diameters. A packaging line that mentions metal is not a metal bit. WORKPRO at about £19.99 names hardwood and has a case, with 4.6 from 757 ratings, a missing 22 mm bit in one review, and snaps after brick. DeWalt DT70751, the same price and 4.8 from 753 ratings, does not list the nine diameters here, and the shank cells disagree. If you need the sizes on the page you are paying, that row fails.

One diameter, or the set with an extension

The single Bosch bit at about £4.95 prints 25 mm in the scope line and 40 mm in the cutting-diameter field. One buyer measured about 39 mm. It grabs if the work is loose, it is softwood and particleboard only, and there is no extension. The Bosch set at about £22.50 states 16 mm to 32 mm plus a 152 mm extension, at 4.8 from 25 ratings. That sample is why it does not beat SHALL, and the bullets exclude hardwood. One review says the pictures showed a circular saw blade. BULLITT at about £18.99 titles a 152 mm bar and 16–32 mm. The table lists no diameters. Reviews mostly name four cutting sizes and call the cut fast but rough.

Rows that fail the title test

haierr at about £8.61 fails if you believed the word set. The bullet says one 45 mm bit, and the rating is 3.8 from 110, next to snaps after a few softwood holes. Some texts say 55 mm. YIWONFU at about £10.63 names hardwood, but the table says stainless steel and the bullets say high carbon steel. The 5.0 line is nine ratings. Berkiin at about £8.99 has no star line. The highlight says a storage box and the bullets say a tube. None of these rows is a hinge-cup bit or an auger. If the chips will pack in thick timber, the spade bit versus auger page is the next decision.

Common questions

Which row is the top pick, and what does that badge mean?
SHALL at about £10.99 shares the highest score with the Gunpla 13-piece set and has more ratings, 1,042 against 493. The badge is that score, not a lab test. Several five-star texts say the bits were unused. The listing says wood, not a stated hardwood.
Which set is the lowest price among the stronger review counts?
The Gunpla six-piece set at about £6.98, with 4.5 from 287 ratings. It stops at 25 mm and comes in a blister. Berkiin is cheaper and has no star line in this scrape, so it is not the stronger sample.
Which listing suits one known diameter?
A single bit, if the diameter is consistent. The haierr bullet is one 45 mm bit, with snap reports. The Bosch single prints both 25 mm and 40 mm. If the size only appears inside a set, buy the set whose bullet prints it.
Why is the Bosch set not the top pick despite 4.8 stars?
It has 25 ratings. SHALL has 1,042. The set is about £22.50, limited to softwood and particleboard, and the 3× line is only against Bosch bit 2609255269. A small sample does not make it suitable for hardwood.
Can I trust DeWalt DT70751 if Amazon lists no sizes?
The reviews cover plywood, doors and some oak, with one bent bit on arrival. This scrape has no diameter list. The pieces cell says 1, the bullets say nine bits, and the shank cells disagree. Keep catalogue diameters off the empty Amazon cell.
Do Amazon stars measure how long the edge stays sharp?
No. SHALL’s 4.7 includes unused texts. haierr’s 3.8 sits next to snaps. YIWONFU’s 5.0 is nine ratings. Berkiin has no star line. A missing size, a bent point or a grab tells you more than the average.
